Solar panels are a great solution for the energy needs of your business. As long as you have enough space, you can get yourself a powerful system that may be able to fully cover the electricity consumption of your business project. In this section of our website you can find a 30kW solar system to your preference. All the components are sized together and match well.
1. The energy consumption of your building ends up as a burden on the budget. A 30 kw solar system helps to alleviate it, if not cover the needs for electricity completely.
2. Solar panels eventually pay for themselves. Payback time depends on the policies in the state and electricity prices, as well on your 30kw solar system price. On average panels pay for themselves in 7-8 years in the USA. The average lifespan of solar panels exceeds 25 years, so you can treat them as a reliable and smart investment.
3. Solar improves the public image of your business. By using renewable energy, you show that you care about the planet and contribute to the fight against global warming.
The PV installations of a large scale are generally grid-tie which means that your house/cafe/gas station or whatever else is connected to the power grid but you use solar energy simultaneously. You can sell excess energy to your utility: it is called net metering and it’s the main way in which a 30 kwh solar system pays for itself.
While off-grid commercial systems of such a scale are a rarity, a 30kw solar system with battery storage can be a good choice if you want to have a hybrid system. Batteries in this configuration will serve as a backup in case of a power outage in the grid. Hybrid inverters ensure uninterrupted power supply but your battery bank should be large enough to take the energy needs of your building on itself.
Large systems are often installed on the ground, simply because often there isn’t enough space on the roof. Panels are cheaper to install this way and it’s easier to turn them straight to south for maximum production. However, a big system requires quite a lot of free space. The exact 30kw solar system size will depend on the power output of panels that you’ll choose.
Modern monocrystalline solar panels vary in their output from around 300W to over 600W. Generally people lean towards 72/144-cell or 96-cell modules when building commercial-size systems, whereas 60/120-cell panels are preferred in residential systems. If you opt for panels that are over 400W in output, a 30000 watt solar system requires from 50 to 75 PV modules. Bifacial solar panels can help you to save space: the active rear side provides up to 33% more production to the rated output of a bifacial module.
The production that you can expect from your system depends on a number of factors, such as positioning, peak sun hours, shading and the weather. For instance, a 30kw solar system produces per day around 150-200 kWh in California in June, but in New York daily production might be lower than 100 kwh.
The most common choice for commercial-scope systems are Chinese solar panels from brands like Jinko Solar, JA, Trina, Longi Solar. Asian panels are cheap and they have high efficiency numbers. North American panels from brands like Mission Solar, Silfab, Aptos Solar are slightly more expensive, but the warranties for them are often better.
The cost of 30kw solar system is going to depend heavily not only on panels but on solar incentives that you might be able to make use of and on the design of your system. Grid-tie systems are the most simple and cheap option. A 30kw solar system with battery storage is going to be significantly more expensive, even though the price of lithium-ion batteries has gone down significantly in the last few years.
At A1SolarStore you can find a 30kW solar panel system of your preferable design. Our managers are there for you to provide any information about the components of our systems, warranties and delivery options.
