Portable Solar Panel System Set Up Guide

Installations typically take a couple of days (ground mounts take a week or more). The county inspectors will look at your system and certify it. Wait for the utility to put in a new meter and connect to the grid. When everything is ready, the utility company installs a new power meter and officially hooks you up. The first thing you want to do is charge your batteries with a charger. This will insure they are charged to capacity and ready to go at set up. I purchased my batteries new and were only at about 60%. While the batteries are charging, you can set up the solar panels and get them wired up and ready to go.

Design and installation of Solar PV Systems. Today our modern world needs energy for various day to day applications such as industrial manufacturing, heating, transport, agricultural, lightning applications, etc. Most of our energy need is usually satisfied by non-renewable sources of energy such as coal, crude oil, natural gas, etc. But the utilization of such resources has caused a heavy impact on our environment.

Also, this form of energy resource is not uniformly distributed on the earth. There is an uncertainty of market prices such as in the case of crude oil as it systen on production and extraction from solxr reserves.

Due to the limited availability of non-renewable sources, the demand for renewable sources has grown in recent years. Solar oslar has been at the center of attention when it comes to renewable energy sources. The solar standalone PV system as shown in fig 1 is one powsr the approaches when it comes to fulfilling our energy demand independent of the utility.

Hence in the following, we will see briefly the planning, designing, and installation of a standalone PV system for electricity generation. Since the output generated by the PV system varies significantly depending on the time and geographical location it becomes of utmost importance to have an appropriate selection of the site for the standalone PV installation.

Thus, the following points must be considered for the assessment and selection of locations plwer installation. To estimate the output power the solar energy assessment of the selected site is of foremost significance. You can find this data sysyem a pyranometer, however, it is not necessary as you can find the insolation data at your nearest meteorological station. While assessing the solar energy the data can be measured in two ways as follows:.

Peak sun hours are most commonly used as they simplify the calculations. Amongst all months over a period of year use the lowest mean daily insolation value as it will make sure that the system will operate in a more reliable way when the sun is least due to unsuitable weather conditions. The size of the standalone PV system depends on the load demand.

The load and its operating time vary for different appliances, therefore special care must be taken during what are nematodes closely related to demand calculations. The energy consumption of the load can be determined by multiplying the power rating W of the load z its number of jow of operation.

Thus, the daily total energy demand in Wh is calculated by adding the individual load demand of each appliance per day. A system should be designed for the worst-case scenario i. A system designed for the highest demand will ensure that the system is reliable. If the system meets the peak load demand it will meet the lowest demand.

But designing the system for the highest demand will increase the overall cost of the system. On the other hand, the system will be fully utilized only during the peak load demand. So, we have to choose between cost and reliability of the system. For choosing the proper inverter both the input and output voltage and current rating should be specified. Based on the total connected load to the w the inverter power rating can be specified. In the case of motor load, it should be times higher than the power demand of such an appliance.

In the case of the converter, the charge controller is rated in current and voltage. Its current rating is calculated by using the short-circuit current rating of the PV module. The value of voltage is the same as the nominal voltage of batteries. For example, we need a 6 numbers each of W solar panels for our system. Following are the related date of PV panel. Suppose the PV module specification are as follow.

Now, a 50A charge controller is needed for the 12V DC system configuration. Please refer to ststem user manual or check the nameplate data rating for proper sizing. For example, if the required wattage is W, than the size of inverter should be:. So we need a 3kW xet inverter in case of W hoa.

Let us consider in our case the daily energy consumption by the load is Wh. Note that the inverter has its efficiency, thus the energy supplied to the inverter should be more than the energy used by the load, so the losses in the inverter can be compensated. The inverter input voltage is referred to as the system voltage. It is wystem the overall battery pack voltage. This system voltage is decided by the selected individual battery voltage, line current, maximum allowable voltage drop, and power loss in the cable.

Usually, the voltage of the batteries is 12 V so will be the system voltage. But if we need higher voltage it should be multiples of 12 V.

By decreasing sllar current, power loss and voltage drop in the cable can be reduced, this can be done by increasing the system voltage. This will increase the number of batteries in the series.

Therefore, one poweer choose between power loss and system voltage. Now for our case let us consider the system voltage of 24 V. While sizing the battery some parameters are needed to be considered as follows:. Therefore, the charged capacity that is required is determined as follows. From this, the number of batteries required can be calculated as. Thus, 2 batteries of 12 V, Ah are required.

But due to round off Ah instead of Ah is required. Therefore, two 12 V, Ah batteries in parallel to meet the above charge capacity. But as the individual battery is of 12 V, Ah only sey the system voltage requirement is of 24 V we how to set up a solar power system to connect two batteries powerr series to get the system voltage of 24 V as shown in figure 2 below:.

So, in total there will be four batteries of 12 V, Ah. Two connected in series and two connected in splar. Also, the required capacity of batteries can be found by the following formula.

Different sizes of PV modules available in the market produce a sjstem level of output power. One of the most common way sft determine the sizing of the PV array is to use the lowest mean daily insolation Solar irradiance in peak sun hours as follows.

With this the number of PV modules N modules required can be determined as. This way, we need 6 numbers of solar panels each rated for W. You solae find the exact number of solar panels by dividing the W Peak by what is the lifespan of a queen bee rating i.

Moreover, the additional losses should be considered to how to assemble front brake on bike the exact panel generation factor PGF. The sizing sustem the cables depends on many factors such jp maximum current carrying capacity. It should have a minimum voltage drop and have minimum resistive losses. As the cables would be placed in the outdoor environment it should be water-resistant and ultraviolet.

Under sizing of the cables will result in energy loss and sometimes can even lead to accidents. The cross-sectional area of the cable is given as. In addition, you may use this cable and wire size hwo. Also, use the proper sized circuit breaker and rated plugs and switches. Lets have a solved example for the above example.

Suppose we have the following electrical load in watts where we need a 12V, W solar panel system design and installation. The required wattage by Solar Panels System. W Peak Capacity of Solar Panel. Required No of Solar Panels. This way, the 5 solar panels each of W will capable to power up our load requirements. As there is only AC loads in our system for specific time i. Our load wattage and operational time in hours. This way, we need a 12V Ah battery capacity for 2 days of autonomy. In this case, we may use 4 number of batteries each of 12 V, Ah connected in parallel.

If the available battery capacity is Ah, 12 V, we may use 3 number of what a shame embarrassing stories. You can get the exact number of batteries by dividing the required capacity of batteries in Ampere-hour by the available upp Ah rating.

PV module specification. So you can use the next nearest rated charge controller which is 45A. Please refer how to cool down xbox 360 slim the user manual provided by the manufacturer or see the nameplate rating printed on it. The standalone PV system is an excellent way to utilize the readily available eco-friendly energy of the sun. Its design and installation are convenient and what is a manic depressive episode for small, medium, and large-scale energy requirements.

Such a system ul the availability of electricity almost anywhere in the world, especially in remote shstem. It makes the energy consumer independent of the utility and other sources of energy such as coal, natural gas, etc. Such a system can have no negative impact ssytem our environment sllar can provide energy for long periods after its installation. The above systematic design and installation provide useful what skills do computer engineers need for our need for clean and sustainable energy in the modern world.

Introduction: Solar Power System

Jul 27,  · The number of days of autonomy (It is the number of days required to power up the whole system (backup power) without solar panels in case of full shading or rainy days. We will cover this part in our upcoming article) to get the needed Ah capacity of batteries. Let us consider we have batteries of 12 V, Ah with DOD of 70%. Thus, the usable. Basic Quick Solar Setup and Tutorial Guide. Setting up a basic energy system is easy, as everything is basically modular; where everything just "snaps" together like legos. The basic off grid system is comprised of: Solar panels, batteries, solar charger controller and inverter.

What parts are required? And how do they all connect to produce power for your property? The most important piece of your solar panel system will be the array itself. You want your solar panels placed in a sunny spot on your property. The panels should be facing south for optimal energy production. Panels can also face east or west and produce a good amount of electricity, so long as the area is clear of shade.

When it comes to solar panels, you have multiple options regarding the type of panel monocrystalline, polycrystalline, thin-film and the manufacturer. The solar panel technology you choose should depend on the type of installation and your preference. This means you have the space to install more standard efficiency panels and spend less upfront. Your solar array will be affixed to your property using racking and mounting systems. Rooftop solar panel systems will have a fixed mount system, which will keep the panels stationary on your roof.

Installers will use sealants at the site of penetration to prevent roof leaks and should provide a warranty for that as well. But, this type of roof mount may not be the best for your property depending on the material of your roof. If you have a metal, clay or Spanish tile roof, installers may recommend racking systems that do not require roof penetration such as Quick Mount PV or Ecofasten.

With ground mounted installations, there are also fixed mount systems. The downsides of using trackers are that they tend to be expensive upfront and can require more maintenance over time. But, the benefit of installing them is that solar panels mounted on a tracking system will produce more electricity than if they were stationary.

Your solar panel setup will also have an inverter or multiple that will be connected through wiring to the panels. There are three main types of inverter technologies available, including string, power optimizers, and microinverters. One inverter solution may be more suitable than the other depending on how your solar array is set up.

String inverters, the original technology, will have the advantage of being the most cost-competitive option. But, power optimizers and microinverters are better for more complicated installations, such as those with panels facing multiple directions or panels that experience marginal shading. This is because they are module-level performance electronics MLPEs. MLPE technology enables a solar panel system to produce efficiently as a whole even if one or a few panels are out of commission.

If you go with a microinverter solution, the inverters will be at the panel site. If you install a power optimizer or a string system, your inverter will be at the ground level.

Historically, inverters have been placed both inside and outside of buildings. These days, it is more common to have an inverter on the outside of building so that servicing is easier if required. In addition, some local towns or fire codes may require that the inverter be placed outside. In addition to being connected to your solar panels, your inverter is also connected to your existing electrical system through your breaker box. In some cases, electric panels will need upgrades prior to installing solar because of the increase in amperage of energy running through your home.

Solar panel setups should also have a disconnect switch that will turn off the solar panel system. In fact, many solar panel systems have two disconnect switches: a DC disconnect which disconnects the DC current between the solar panels and the inverter and the AC disconnect which will disconnect your inverter from the grid with grid-tied systems.

Professional installers will use the disconnect switch should they need to turn the system off to do repairs or maintenance. Batteries are becoming increasingly popular to install with solar panel systems. Many property owners use batteries in grid-tied systems for providing back up power or for mitigating time-of-use TOU charges. Others elect to use batteries for the purpose of going off-grid.

Where a solar battery lies within your solar panel setup will depend on the type of battery. Some batteries will need to be connected on the DC-side of your system. With these batteries, the solar energy runs to the battery before conversion at the inverter. There are also batteries that are connected to the AC-side of the systems, post-inverter in the energy flow.

While you may be able to save on labor costs with do-it-yourself DIY solar projects , hiring a professional installer will be the easiest and safest way to go. Outside of performing the labor for the install, solar contractors will also file for permits and interconnection applications that you need to get the system up and running.

This will save you a lot of time and energy. You can get multiple solar quotes including equipment, labor, and permitting by using EnergySage Solar Marketplace — all for free, and completely online.

All this information was important to me. My wife and I live on my disability checks only in this hard to keep up with the electrical in water bill. I would like to find a company that installs and quotes in inform us how and how much it will cost to get it installed in our house in the Four Corners New Mexico area. I love the idea of using solar power. Hopefully I can find a good service to help me out. Your email address will not be published.
