12-16 panels
How many solar panels to supply an average household? A typical home is approximately 1,500 square feet (153 square meter), with electrical costs of about $100 per month (70 Euro). Such a house generally needs about 12 to 16 panels to completely cover electrical power needs. 

Optimizers take DC energy, regulates the output of the module and delivers energy to the central inverter for final DC to AC usable energy conversion. The optimizers increase the overall energy output of your PV array by consistently tracking the maximum power point (MPPT) of each individual module in your system.

25 – 30 years
How Long Do Solar Panels Last? Depending on the manufacturer, solar panels’ performance can be guaranteed for 25 – 30 years, but it’s very possible that your panels will go on to produce electricity for longer than that. Panasonic Solar panels are guaranteed for 25 years by Panasonic.
