7kW Solar System

7kW solar system

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 A1 SolarStore 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.

How much does a 7kw solar system produce

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:

• Weather and hours of sunlight. Panels keep working when it’s cloudy, but their performance drops by 20-40%. Some areas get more sunlight than the others, and the more sunlight the system gets, the more it produces.
• Positioning. If you live in the US, turn your panels to the south. An angle can be equal to your latitude or you can just set it between 30 and 45 degrees. It is easier to set up a 7000 watt solar system on the ground perfectly but it will require more maintenance.
• Shading. One shaded cell of a solar panel can shut down a whole sector of a module. Moreover, the performance of every panel drops to the level of the weakest link, if you’re using a simple string inverter. Add solar optimizers to decrease the impact of shading on your system.

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.

7kw solar system cost

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.
