A photovoltaic system is a smart energy solution for home or your enterprise. The industry is on the rise: the cost of solar panels decreased by 80% in the last decade while electricity rates are going up. Since the state still encourages and incentivises people to go solar, there is no better time for it than now.
The systems can be different and vary depending on their purpose though. There are three most popular types of systems and the PV system components to build them can be different:
Grid-tie photovoltaic system for home consists of 10-30 panels and an inverter which is connected to the grid and turns direct current from panels into alternating. Notice that this type of a system is reliant on the grid and shuts down during a power outage.
Off-grid PV system consists of panels, batteries, a charge controller to keep the batteries safe, and an inverter to convert the DC to AC for appliances.
A hybrid solar photovoltaic system is made out of solar panels, hybrid inverter, a battery and charge controller to protect it. Sometimes a hybrid inverter has a built-in battery and a controller. Hybrid system is a great solution when you can’t risk losing power even for a short period of time.
The initial PV system design is important to figure out at the start, but later on you often can change the configuration of your system. For example, an off-grid system can be transformed into a hybrid one by replacing an inverter and adding batteries. Keep in mind, however, that the interconnection process, where you connect the system to the grid, should be negotiated with your utility company first.
Solar system consists of dozens of solar panels so they are going to be your main expense. The photovoltaic system cost highly depends on the brand of panels. Chinese companies Trina and JA Solar have the cheapest panels which are fairly efficient as well. North American brands Mission Solar and Canadian Solar, for instance, try to balance things out: their panels are powerful and quality and the price isn’t too high either. Panasonic, REC, LG offer the most expensive panels that are packed with innovations and are of the highest quality.
Inverter is the most fragile part of your PV system, so we would recommend getting a quality one. The most standard choice is a string inverter, but you can also go for microinverters. They are easy to install, efficient and last just as long as solar panels themselves. However, the maintenance can be more problematic since all of your inverters are on the roof. Besides, going for microinverters increases the final photovoltaic system costs.
If you want to get a rough estimate of how much a system can cost, we suggest using our solar calculator. This simple tool allows you to create your dream system in just a few minutes. You enter your electricity consumption data and zip code which allows the tool to load up the electricity rates in your area. Then it starts sizing PV system that will cover up to 85% of your energy consumption. You can choose any panel from our store to build your installation with. The calculator provides not only a cost estimate, but also potential savings, area that the system needs, and the amount of taxes that you can get back through the Federal Solar Tax Credit program.
We offer all kinds of equipment for solar systems for sale and our staff will be glad to help with your order and answer all questions concerning PV system size, shipping, prices and everything that you might have a problem with. Here is how we operate:
