Contrax reviews roof condition, orientation, shading, electricity consumption, tariffs, electrical capacity, available equipment locations, EV charging needs and any circuits the customer may want supported during an outage. The resulting proposal explains the recommended equipment, scope and design assumptions.

We assess roof condition, orientation, pitch, shading, available area, access and likely structural constraints. Electricity use and tariff data are also reviewed so the proposed array and any battery storage are sized for the property. A structural assessment may be required before installation.

Yes. Solar PV continues generating in daylight when skies are cloudy, although output is lower than in strong sunshine. The proposal uses site-specific modelling and historic irradiance data. Actual generation varies with weather, shading, system condition and electricity use.

No. Solar PV can be installed without battery storage. A battery such as Tesla Powerwall 3 may increase the amount of generated electricity used on site and can provide backup capability when that feature is included in the approved design. Suitability depends on consumption, tariff and project goals.
