20kW Solar System
20kw solar system
The energy needs of a business can be significant, but a PV installation may be an answer to your problems. A 20 kw solar system will cover, at least partly, the energy consumption of your business and pay for itself in less than a decade. At A1SolarStore we offer complete systems where all the components already go well together.
What is 20 kw solar system
Commercial solar systems are for the most part grid-tied and they are often installed on the ground, since there isnât enough space for the modules on the ground. A 20 kwh solar system is usually built out of large 72/144-cell or 96-cell PV modules. These panels are over 400 Watts in output. You would need a substantial amount of modules to construct a large PV installation: for example, you could use fifty 400W solar panels.
Ground-based installations are usually slightly cheaper to install than rooftop systems. It is also easier to get the best positioning and angle for your modules. However, land installation requires quite a lot of space (the exact 20kw solar system size will depend on the modules that youâll choose). You can choose bifacial modules with an active rear side to save space. Bifacial panels provide up to 33% bonus production, if installed correctly.
How much power does a 20kw solar system produce? A lot depends on the positioning of your panels, their properties, shading and number of sun hours in your area. Generally, the number of peak sun hours ranges from 3 to 6 per day. In the summer panels produce 50% more energy than in winter. For instance, in June a 20 kilowatt solar system in Los Angeles may produce from 100 to 120 kWh of power per day.
While grid-tie configuration is the most common choice, you can also get a 20kw solar system with battery storage. A battery bank will keep your house or business project powered during power outages. A hybrid system ensures uninterrupted power supply which is important when you canât risk losing the results of your work over a blackout.
20kw solar system cost
Panels play a big role in your systemâs production and its cost. Generally, Chinese PV modules are used because of their low cost and high efficiency. The most famous brands from Asia are Jinko, JA, Trina, LONGi Solar. North American panels are also a good choice: they are a bit more expensive but the quality is higher overall. Companies like Panasonic, LG, REC offer premium-class panels primarily for residential systems so going for them will greatly increase your future 20kw solar system price.
Grid-tie system is the most simple and the cheapest configuration â it only requires solar panels and an inverter (possibly, several units). The cost of a 20kw solar system with batteries for hybrid or off-grid variations is going to be significantly higher. Lead-acid batteries are cheaper, but lithium-ion ones allow for deeper discharge, last longer and are more efficient.
