Hi,
My parents finally have PV solar panels on their roof .
I have been trying to convince them to install it ever since they have moved in this house. I had the idea of a really green house. A grey water system, cistern, roof PV solar panels, wind turbine, compost and a green house 
and it slowly goes there.
Unlike the cistern, this isn’t only ecological, but also profitable. The rates are slowly dropping, but the system will still cover the annual electricity bills (around 12,140 ₪ = 3600$ 
).
For Israel solar systems are probably the best way to produce green electricity – no water power and not much wind power. In Israel, we are using solar power for years to heat water for private use. Those save 3%-4% of Israel energy consumption energy.
There is already big solar field in Israel in Ashalim (not to be confused with the two other solar thermal energy power stations). The power plant supply 30MW, while the new wind turbine farm in Emek HaBacha in Golan Heights will supply 96 MW.
But the massive amount of solar electricity is produced by the panels on top of roof, just like those on my parents roof. Most of the education buildings I check for safety hazards or Earthquakes are covered by panels, as well as many private houses, stables, gas stations, factories etc…
Those produce around 1,800 MW. A lot, but solar energy is only 7% of Israel energy consumption, not enough to reach the goal of 10% of total renewable energy.
As part of EWB project we installed a Solar panel in the Negev, for an isolated Bedouin house. It was cheap, clean, fast and supplied the electricity needed to hold cold the kid medicine.
Take Care

The installed PV solar panels. In a week IEC worker will change the electric meter and connect it to the grid.
