> Dear Madame/Sir,
>Here two questions from sunny South Africa.

>We in Johannesburg are on the same

>the same number of sunny days
>per year. Some of us (who
>are not born here) don't understand
>how comes that Solar energy, in
>all it's forms, is not utilized
>in this country and in this
>region. Accordingly, we have to inquire
>about Solar Energy all the way
>in Europe and North America. Here
>are two questions:
>- In this region, during the summer,
>we have short yet very strong
>thunderstorms with lightnings. Lightnings are so
>strong that one can speak of
>electrical storms. What is the impact
>of lightnings on PV systems?
>- There is an abundance of bird-life
>in this region. How does one
>prevent birds from nesting on solar
>panels and/or leaving their droppings there?
