Here’s how to calculate solar panel, solar battery and inverter size.
Generally, you would go for a 5 – 6.6kWh system depending on your home’s specific power needs. The cost of installing a solar panel system is factored into the price of the solar system. Manufacturers test solar panels’ performance in Standard Test Conditions of 77 degrees Fahrenheit.
You can't stomach the maintenance

The tariffs for exported solar energy can vary from supplier to supplier, but a good rate is 4-6p/kWh.
Solar panels are a big investment, so it’s important to calculate the cost. Each home has a different demand for power and electricity consumption, so we need to work out the cost per square foot. The cost of ownership includes the maintenance costs, which must be discounted to find the NPV. The LCOE can then be compared to the cost of electricity from a utility; remember, the relevant price is that which occurs during times at or near peak PV solar production. One of the most important considerations is the solar irradiation levels available in the home's geographical location; in other words, how sunny it is where you live.
