Understanding Solar Panel Decommissioning: Why, When, and

The question of solar panel decommissioning is an important one. Solar panels don''t last forever, and it''s important that they be taken care of properly when they need to be removed from service. Here, we''ll look at what exactly decommissioning means, why it''s necessary for the longevity of your solar panels, and how you can ensure this process goes

Why are Solar Panels Good for the Environment?

The devil we know. To understand why solar panels are so good for the environment it helps to know why the status quo is so bad. At present, according to a YouGov report, renewable energy accounts for 47.3% of the UK''s energy.While that figure is encouraging, it means that over half the power we produce either comes from fossil fuel or nuclear power.
