9kW Solar System

9kw solar system

Solar system is made out of several components and solar panels themselves are just one of them. You have to size all parts together well so that they function properly. At A1SolarStore you can order a complete solar system where all the parts are selected by our engineers. We offer systems of a different design and you can use them for your home or a business.

What is in a 9kw solar system

Every solar panel system always has solar panels and an inverter. Solar panels produce direct current under the sun and the inverter turns direct current into alternating which is suitable for all the appliances in your house. Now you may ask “how many panels in a 9kw solar system are there?” The answer depends on the wattage of your PV modules. You can build a system with 30 300W modules or can go for 500W modules and you’ll need only 18 of them.

The exact components of your system depend on the configuration that you’ll choose. There are three types of systems: grid-tie, hybrid and off-grid.

• Grid-tie 9 kW solar system is the most popular and simple type. Generally, it consists only of solar panels and an inverter. Your house is connected to the grid and you can use either solar energy from panels or electricity from your utility. The main benefit of this configuration is net metering: you can sell your energy to the utility and get credits to pay your bills.
• Hybrid system is a grid-tie system with energy storage. You need a special hybrid inverter for it. When a power outage happens, the grid-tie solar system shuts down. However, the hybrid system keeps on working: an inverter switches your house to battery support. Sometimes a hybrid inverter has a built-in battery and charge controller: if it doesn’t, they come separately in a 9kw solar system kit.
• Off-grid system implies that you don’t have a connection to the grid. It’s a great choice for standalone houses in remote locations: in the forest or on the seashore. Off-grid system consists of PV modules, an off-grid inverter, batteries and a charge controller. Since energy storage is pricey, a 9kw solar system with batteries is significantly more expensive.

Please note that a solar kit doesn’t have a lot of wiring in it. The reason for this is that the length and size of your wires can vary greatly, depending on how you want to set up your installation. We don’t want you to overpay for wires that you might not need, so that’s why you or your installer should purchase wires and cables on your own.

Now you might wonder, how many kwh does a 9kw solar system produce? The answer depends on a set of factors like shading, weather, efficiency of your panels and most importantly, sun hours in your location. For instance, in California the average number of peak sun hours throughout the year is 5.6, thus a system generates around 9 kW × 5.6 h = 50.4 kWh per day, give or take. Keep in mind that a 9000 watt solar system is going to produce around 50% energy in June compared to December.

9kw solar system cost

Solar panels can be considered a long-term investment. Generally, a PV installation pays for itself in 6-8 years. Given the fact that panels last over 25 years, you can expect to get your money back at least 2-3 times.

However, the upfront cost of 9kw solar system can be high. To avoid it, you can apply for solar loans with a low interest rate — such programs are active in almost every state. Don’t forget to take advantage of the Federal Solar Tax Credit which allows you to get back 26% of your installation costs through taxes in 2022. You can also lease a system but the savings from it won’t be as high in the end.

Panels play a big role when you choose a system. Going for Chinese-made PV modules can substantially lower your 9kw solar system price. However, American brands offer solar panels of a higher quality. The best modules come from companies like Panasonic, Sunpower, REC, Solaria. Their warranties are the best, but the panels are quite expensive.

So how much does a 9kw solar system cost? You can expect to pay anywhere from $15,000 to $25,000, depending on the design of your system, available incentives, solar panels and the installation service. Keep in mind that it is cheaper to install solar panels on the ground than to put them on the roof, but they’ll occupy important space and they’ll require more maintenance, such as cleaning.
