What roofs are not suitable for solar panels?
Roofing materials that are not ideal for solar include wood and slate roofs. For one, these roofing materials are brittle, so solar panel installers can’t just walk around on the roof as they normally could. This makes for a more difficult and, therefore, more expensive installation process.
How are solar panels fixed to a tiled roof UK?
Solar PV panels can be retrofitted onto an existing roof, on top of the tiles or other roofing materials, using roof anchors (also called roof-hooks or brackets), mounting rails and clamps. Mounting rails are usually made of aluminium (due to its lightness) and other components from aluminium or stainless steel.
Do solar panels damage tiles?

How long do solar panels last?
25 years
Solar panels, also known as photovoltaic or PV panels, are made to last more than 25 years. In fact, many solar panels installed as early as the 1980s are still working at expected capacity. Not only are solar panels remarkably reliable, solar panel longevity has increased dramatically over the last 20 years.
How long do concrete roof tiles last?

What are the 2 main disadvantages to solar energy?
Disadvantages of Solar Energy
- Cost. The initial cost of purchasing a solar system is fairly high.
- Weather-Dependent. Although solar energy can still be collected during cloudy and rainy days, the efficiency of the solar system drops.
- Solar Energy Storage Is Expensive.
- Uses a Lot of Space.
- Associated with Pollution.
Can you walk on a tile roof?
To avoid a serious fall, only walk on completely dry tiles. For steep roofs, use a safety harness that will anchor you to the roof in case you slip. Soft-rubber-soled shoes, like sneakers, will limit breakage and give you better traction on the slippery tiles, compared to heavy shoes or boats.
