In general, photovoltaic modules last for 20-30 years.
※ Life expectancy of it differs by the condition of place.
Can I increase volume later?
If inverters have room for capacity, it is possible to increase same stock number and same series number of photovoltaic modules.
If inverters don’t have room for capacity, you need to construct new system.
Do I need inspection or maintenance?
It is not obligation to have regular inspections for photovoltaic modules and inverters. Also you don't need special care.
However, we recommend you to have regular inspections by your construction shop for long term use.
We also recommend you to have inspections after typhoons and earthquakes.
(Please burden inspection fee at your expense.)
Do you have insurance?
Each manufacturer has different insurances, so please contact us for more detail.
Do I need daily operation after instruction?
No, you don' t need it. Photovoltaic system starts with sun rise automatically, and it stops with sunset automatically. You don't need any troublesome operation.
