A home solar system drives your bills down and makes you less reliant on utility. When choosing panels for your home, pay attention to the brand, the warranties and the power output. The design is important too — consider all-black panels! If you need a powerful system and the space is limited, prioritize high efficiency. Look for panels with a conversion rate of at least 21% of higher.

Alexey Kruglov, A1 SolarStore CEO

A PV system is a great choice for businesses. It lowers your energy expenses and improves brand image.

The line between residential and commercial solar panels is blurry. Generally, PV modules with an output over 450W are considered commercial. They are larger than home panels and are harder to fit on the roof. That’s why commercial systems are often ground-mounted. Bifacial solar panels with an active rear side are popular in large installations.

Panasonic and Sunpower panels can be twice as expensive as panels from a smaller company but they aren’t twice as good. Don’t overpay for brand!

The cheapest solar panels come from Chinese companies, such as Trina Solar, Jinko Solar, JA Solar and others. Low cost and high efficiency are their main advantages. However, the warranties for them can be short: around 12 years. Depending on the relationship between the US and China, they are sometimes hard to come by.

American-made solar panels are often more expensive than Asian PV modules. In return, they often have better warranties and are easier to get. Customer service is also more accessible — not that solar owners need much of it. American brands don’t always make solar in the US though — some outsource the manufacturing to Asia.

Consider AC panels that come with built-in micro inverters! The system is going to be more efficient and shade resistant.

Among our customers, 400W solar panels are the most popular. They are a great choice for either a home installation or a small business project. The most efficient solar panels are rated for 400W or around that number, with some going over 22% in efficiency. High efficiency becomes important when you're dealing with limited space.

I was new to the Solar Panel Industry, just browsing for information when I came across A1 SolarStore. After doing researching and educating myself on products through their easy to navigate website I made my first purchase. I couldn't be happier by choosing to go through A1. The customer service I received was very beneficial on choosing Suntech 370 W Solar Panel. Best part of A1 is that the pickup locations was extremely convenient only miles from my home.

If you are looking to purchase Solar Panels, I would highly recommend A1 Solar store. I did not have much knowledge on Solar Panels and/or the benefits of them. A1 SolarStore customer service and knowledge of their panels was outstanding. My purchase of the Silfab 400W panels was made easy and quick with a pick up location right in my area.
