J & M Costa now specializes in solar panel installation’s for new homes and existing homes.

Solar panels harness the sun’s energy and convert it into electricity using advanced photovoltaic (PV) technology, providing clean, renewable power for your home. By reducing your reliance on the electricity grid, solar energy can help protect you from rising power costs, lower your household’s carbon footprint, and potentially increase your property’s value.
Whether you’re looking to save money on energy bills, improve your home’s sustainability, or invest in a smarter energy future, J & M Costa can help you make the switch to solar with professional installation and expert advice.

•How solar panels work
When sunlight strikes the silicon cells within a solar panel, it energizes electrons and generates direct current (DC) electricity. An inverter then converts this DC power into alternating current (AC), which is the form of electricity used by household appliances and lighting.

•Government Incentives and Rebates
A range of government incentives and subsidy programs can help reduce the upfront cost of installing solar. While these schemes continue to provide significant savings, available incentives are gradually decreasing over time, making earlier adoption an attractive option for homeowners looking to maximise financial benefits.
