What Raglan homeowners ask about solar

How does shading affect solar panels in Raglan?
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.
Is my roof suitable for solar panels in Raglan?
Most roofs are suitable. You need at least 15-20 m² of unshaded roof space for a typical 4kWp system (10 panels). South, east, or west-facing roofs work well. Your installer will assess your roof's orientation, angle, and structural suitability during a site survey.

Do I need a smart meter for solar panels?
You need a smart meter to sell surplus electricity back to the grid under the Smart Export Guarantee (SEG). Your energy supplier will install a smart meter for free. Your installer submits the G98/G99 application to your DNO after installation.
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.
