What are those workmen doing on the roof of the house across the
street ? |
Gene |
I talked to one of them when they arrived this morning.
They're fitting a solar panel. |
Ruth |
What's that for ? |
Gene |
It's for heating water using just the heat of the sun. |
Ruth |
Can you really get enough heat from the panel to do that ? |
Gene |
Well, it depends on the weather of course, but he told me that it
can provide from 30% to 70% of an ordinary home's needs for hot
water per year. |
Ruth |
And for free ! That's really worth having. |
