What Porth homeowners ask about solar

How does shading affect solar panels in Porth?
Shading from trees, chimneys, or nearby buildings can reduce output significantly. Modern systems use optimisers or microinverters so that shading on one panel doesn't drag down the whole system. Your installer will assess shading during the site survey.
What happens to my solar panels if I move house in Porth?
Solar panels stay with the property as a permanent fixture. They add value to your home for the next buyer. Your installer can transfer monitoring accounts to the new owner.
How long do solar panels last?
Modern solar panels are warrantied for 25-30 years and typically last even longer. Panel efficiency degrades by about 0.5% per year, so after 25 years, your panels will still produce around 87% of their original output. Inverters typically last 10-15 years and may need one replacement.
What is the Smart Export Guarantee (SEG)?
The Smart Export Guarantee (SEG) requires licensed energy suppliers to offer a tariff to small-scale generators for electricity exported to the grid. Rates are typically 3-15p/kWh. You need a smart meter and an MCS-certified installation to be eligible.
How long does solar panel installation take?
A typical residential installation takes 1-2 days. This includes scaffolding, mounting the panels, wiring, inverter installation, and connecting to the grid. Your installer handles the DNO notification (G98/G99 application).

Yes. Solar panels improve your EPC rating and can increase property value by up to 4%. Buyers increasingly look for energy-efficient homes with lower running costs. A solar system in Porth is a long-term investment in your property.
