RESIDENTIAL Solar power system・Mega Solar GRID Inc.
An Eco Solar Lifestyle
Solar power generation is a superior technology that combines aspects of both ecology and economy,
including fighting environmental problems by reducing CO2 emissions that contribute to global warming,
and reducing the day-to-day utility costs by selling the surplus power generated.
The power generated annually when installing the 6.360 kW system* is approximately 6,645 kWh.
This is equivalent to reducing CO2 emission down to approximately 2,090 kg-CO2.

*1: If installed in Tokyo area, facing southward and with 1/10 roof inclination
*2: Solar power system reduces CO2 emissions to, [0.3145 kg – CO2/kWh x power generated annually]
Power generated by solar panels can be used at home, with any additional reserves becoming surplus electricity,
which can be “sold” to energy companies for income. Reducing power usage during peak periods for generating power will greatly increase surplus electricity to sell,
with the added bonus of not only extra income, but overall reduction of utility bills.
Even in cases of power outages when energy companies are unable to supply electricity,
switching the power conditioner to autonomous operation mode during sunlight periods can make it possible to use the power generated from the solar panels.

GRID provides a system guarantee for a long-lasting and safe use of the solar power generation system.
For details regarding the guarantee, please ask your dealer when purchasing.
Even after installation, if the solar panels begin degrading or become defective over the years leading to ineffective power generation, the merits of such a system will become pointless. We guarantee nominal maximum output of 90% or more 10 years after installation, and 80.2% nominal maximum output 25 years after installation.
*Guarantee only applicable to REC modules.
*Output guarantee of GRID panels is 10 years. If the output value of the GRID solar panels installed within 10 years does not meet our specified value (*1) due to defects in the product, product will be replaced. “*1: Specified in JIS C 8918-6.1 (Performance), as 90% of the lower limit (90% of the nominal maximum output) of the maximum output by the solar panel.”
System device has a 10-year warranty. If there are malfunctions and defects of the product even though it was used in accordance with the instruction manual, etc. (*2), the product will be repaired or replaced with an equivalent product.
Warranty applicable to (*3): solar cell panels, power conditioner, junction box, PV cable, standard mounting frame for residential use
*2: The 10 year warranty for the solar power generation system device will only apply to customers, or the 10 year guarantee commissioned by the customer. It is necessary to complete the prescribed procedure at the issuance registration dealer.
*3: Warranty period for the display monitor is 2 years. Not subject to the 10 year warranty for the solar power generation system device. We appreciate your understanding.
*Warranty does not apply to product defects due to construction and modifications after purchase.
*Warranty and Disclaimer details are provided on our warranty certificate.
