Photovoltaic cells on top of someone’s roof will no longer be a sight of interest for people visiting or living in Spain. In fact, they’re simply going to become part of the building code thanks to new legislation that requires all new or renovated buildings to offset “between 30 and 70 percent of hot water costs with the sun.”
From the article,
“New non-residential buildings, such as shopping centers and hospitals, now have to have photovoltaic panels to generate a proportion of their electricity. Other measures in the new building code enforce the use of better insulation, improve the maintenance of heating and cooling systems and increase the use of natural light.
“The new standards will bring energy savings of 30 to 40 percent for each building and a reduction of carbon dioxide (CO2) emissions from energy consumption of 40 to 55 percent,” the Environment and Housing Ministries said in a joint statement.”
Wow. If I was an investor in Solar technology, I would be all over the companies bidding for contracts in Spain after this announcement. The question is, what kind of pressures will this place on the industry such that demand will outstrip supply? Quality silicon for solar panels are already in short supply. I wonder if a delay of this kind would delay the entire renovation or construction of a new building?
