It depends on how much electricity you use, when you use it, and the space available. We review your electricity bills and loads during a site survey and size the system accordingly.
On-grid systems work with the utility supply and need no batteries. Off-grid systems run independently with batteries. Hybrid systems combine both, so they can keep essential loads running during power cuts. We recommend the right type after understanding your needs.
Yes. Panels still produce electricity on cloudy days, although output is lower than in full sunshine. Systems are sized with seasonal variation in mind.
Mainly regular cleaning of the panels to remove dust, and periodic inspection of connections, protection devices, inverters and batteries. We offer maintenance and inspection services.
