The average household requires about 20kWh per day which is serviced by a 5kWh solar system. However, from household to household needs differ, appliances and applications differ. So it is best to get a detailed assessment of your own home or offices energy consumption on a mean (an average over the year, with highs and lows factored in) in order to know with certainty what you will need.
Costs of a system vary from home to home, and how the investment is financed or funded.
It is difficult to answer this question given that solar systems are funded or financed differently. But the average ROI (Return on Investment) period takes 5-7 years, after which the system gives free energy.
This depends on which brand and type is purchased. Lifespan of panels is said to be upwards of 20 years, with some stating 25 to 30 years. BUT, this depends on the make and type.
The best battery currently is the supercap battery. THis is followed by the more broadly used Lithium Ion Battery and then the Gel battery, lastly the Lead Acid battery.
A hybrid Solar System runs on solar power and/or mains power, with battery backup for power outages or period of no sun. All excess power generated by the solar panels is able to be returned to the grid - should this be available in your area.
Solar systems are designed to be scaled. This really means that at design you factor this in by investing in the correct foundational equipment that you can then duplicate (inverter and panels) and more batteries should more backup power be needed.
