Go Solar The Better Way.

Solar savings

Own Your Power and Pay Less

The rumors are true. Solar is not only the right decision for the planet, it’s also the right decision for your wallet. We size every system to your daytime use, because since Ministry of Energy Regulation No. 2 of 2024, power exported to PLN no longer reduces your bill.

Premium aesthetics

Designed With You in Mind

Premium Tier-1 systems are our first choice for every installation. With LEIN Power, your home or building will look like it’s from the future, increasing curb appeal and attracting buyers if you ever decide to move.

Peace of mind

Clear Warranties, Supported Claims

On top of the manufacturers’ equipment warranties, we give a one-year workmanship warranty and a ten-year warranty on the mounting structure, and we handle warranty claims at no service fee, excluding import duties and taxes, shipping and reinstallation.

How Solar Works for Brighter Living

Illustration: a two-storey tropical home with 24 solar panels on the roof, and an inverter, backup box and battery on the marble wall by the garden
The sun is rising, everything is coming to life. Energy consumption increases. There is not enough solar energy yet, so power must be obtained from PLN.

kW figures rounded from one day of data from a LEIN hybrid home system (7.74 kWp, 15 kWh battery); on-grid uses the same data without the battery. Cloudy, Rainy and Blackout are simulated. Image: illustration, not a LEIN project.

Product Brands We Use

LEIN Power partners with principals and authorised distributors for every component of the solar system — modules, inverters, batteries, cables & connectors, protection & switchgear, mounting and monitoring — so that availability, product authenticity and manufacturer warranty service are assured; energy simulations are run with industry-standard software. As our primary option we propose modules, inverters and batteries from Tier 1 manufacturers — listed in the BloombergNEF (BNEF) Tier 1 List and/or S&P Global’s Tier 1 Cleantech Companies, the bankability benchmarks used by financiers. On request we can also offer other brands that have passed our technical qualification as a more economical alternative, still with the manufacturer’s warranty and LEIN’s after-sales support.
