How much power does a 20kW Solar System produce?
On average your 20kW Solar System can expect to produce around 70kWh to 100kWh of power daily. The actual number will vary from day to day as it depends by the average sunlight in your area, the weather, and the placement of your Solar Panels.
Typical financial return and payback period for a 20kW Solar System
Over its 25-year lifespan, a 20kW Solar System can generate approximately $208,050 of power based on $.30c per kw. On a yearly basis, a 20kW commercial Solar System can generate approximately $8,322.
Estimated solar generation is calculated by multiplying the number of estimated panels, the wattage of each panel, and the average number of sunshine hours per day. This calculation is based on a $0.30 per kWh electricity rate and is projected over a period of one year and twenty five years.
Do I need a Battery Storage for my 20kW commercial Solar System?
The most significant advantage of Solar Batteries is that they can provide power during power outages. With climate change causing more extreme weather events like cyclones and flooding, power outages are becoming more common in New Zealand. During an outage, a Solar Battery Storage can provide you with a reliable backup power supply, allowing you to maintain your business as usual.
