Overview of the 3.9 kWp PV System

As soon as the DHW system did work, I thought of the future more far away, when my kids grow up and need more money. Some investments had to be done. So what about installing a PV System?

My decision was based upon

• I knew I had money to invest right now, limit about 25'000 EUR
• I don't need the return right now, but will love to get it in about 10 years
• I own a firm that gets some provisions, which need to be invested
• The subventions are high at the moment (63.25 ct/kWh incl. tax), guaranteed for 20 whole years plus the installation year
• I had a roof to spare - although 255 degrees WSW, so not perfect

Thus I decided that 'Kaiser Software Engineering' will go straight into the energy market.

After some research in this area (and a lot of firms don't bother to answer, or to send any notice that I succeeded in sending them a fax or email), I found one firm in Freiburg, which

• sent me a fast and competent reply
• sounded very experienced
• showed that experience in their offer
• had a very long reference list (and one reference customer I called was very convinced of their work) - although they don't keep that list up to date, I'm not in it)
• had little problems to get panels (other firms repeatedly told me how hard it is nowadays...)
• had a good reputation in Freiburg
• exists since 1987

so I decided to give them the chance. After sending the roof plan, a picture taken from an airplane, and the maximum amount to spend, we exchanged some eMails, had some telephone conference, the CEO (who was in my area on vacation) came by here for an hour and looked around, took some measurements, gave me a schedule, and went.

And so the installation went - the mechanics came (in time), installed the system in two days' time, and went. And everything works since then. Everything done, including all paperwork. All their hints were helpful. Not bad! That's exactly how it should be.

Also, they are very friendly and still answer any mail (even after the installation is finished and the deal completed), usually on the next day. I write in the evening, when I have time, and the next evening the answer is there. This is not always the case! My choice seems good.

Again (trust me), I don't get anything from that firm. I'm just convinced they do a really good job, and I would immediately do it again.
