20kw solar with a battery storage

Even though we don’t recommend any battery systems at this time, that is likely to change in the near future. All solar systems we supply can have battery storage systems installed, using AC coupling. This allows you to connect a battery to any property, as it connects directly to the main power supply. If you were looking to add a battery storage option to a 20kW solar system package you will be able to use the power produced during the day, for use at night. Saying that, battery backup options are quite expensive, and tend to greatly increase the repayment period of your investment. Talk to us and we will be happy to advise you if this is the right option for you.

In conclusion

A 20 kW solar system is a relatively large power plant, and the biggest that most residential situations will allow. However, it is ideal for commercial premises; if you have the roof space and consistently high daily energy consumption. The amount you can save from a 20kw solar power system depends on the power it can produce for your business and your power needs. The amount your business can save by installing a 20kw solar PV system will depend on how much you pay for electricity, and how much electricity you use. We can help you work that out.
