When you want to build a solar system for your house or business, it’s important to size together all the components of it. For a newcomer to solar energy and electrics, it might come off as a challenge. At A1SolarStore you can order a complete solar system where all the parts fit together well.
A 7kw solar system, grid-tied or off-grid, is a smart energy solution for a medium-size or large house. It should be able to cover up to 100% of your energy needs, especially in a sunny place.
The production that you can expect from your PV installation depends on your panels just as much as on the set of external factors. Here are the most impactful factors that you should look out for:
So how much power does a 7kw solar system produce per day? It depends on the number of peak sun hours in the area. For instance, the average number throughout the year in California is at 5.6 hours. Thus, a system makes close to 40 kWh per day. Keep in mind that a system makes 50% more energy in summer than in winter.
The drawback of a solar system is a somewhat high upfront cost. However, this problem can be avoided by applying for incentive programs and getting special solar loans at a low interest rate. By selling energy into the grid, you gain money with your system and eventually it pays back for itself. The average ROI time of a solar installation in the US is 6-8 years, whereas the average lifespan of solar panels surpasses 25 years.
The cost of 7kw solar system highly depends on the panels that you’ll choose. You would need from 15 to 25 panels to build an installation. Chinese panels from brands like Jinko, LONGi, JA, Trina Solar are the most affordable. The PV modules from NA brands are slightly more expensive but their quality is higher. The most efficient and reliable but also the most expensive panels come from manufacturers like REC, Panasonic, LG, Sunpower.
The overall 7kw solar system price can vary from $8,000 to $15,000, including shipping and installation services. You should always take advantage of the Federal Solar Credit program which is available in all states for owners of residential and commercial PV installations. It allows you to receive back 26% of your 7kw solar system cost through taxes. It makes sense to hurry: in 2023 the percentage drops to 22% and in 2024 and subsequent years it falls to 10% and applies only to commercial systems.
