Guide for applying for photovoltaics in Spain

“This Guide describes the steps necessary for the processing of power generation facilities in self-consumption of any of the modalities provided for in the regulations, both for individual self-consumption facilities, and for installations in collective self-consumption. It is aimed at the general public, but more specifically to the companies that install self-consumption systems.” – Google Translate of the text on the page of the link.

Solar air conditioning on ice

“IceBear 30” units from the company Ice Energy can eliminate up to 5,000 kg of CO2 per year, according to themselves


“This is transforming commercial air conditioning load into a clean and flexible grid resource”.
The benefits should amongst others be
  • Efficient: Reduces peak cooling load by 95% and delivers 100% round-trip efficiency.
  • Reliable and cost-effective: Resigned to last 20 years, each unit only requires a one hour annual maintenance procedure.
  • Easy to install: Integrates seamlessly with packaged or split HVAC units
  • Green: Lowers CO2 emissions by up to 5,000 kilo per unit per year without generating any hazardous waste.

IceBear eliminates the need in peak hours to turn to fossil fuel-burning additions gas peaker plants. Furthermore, using solar or wind energy, it can store the energy as ice directly as “cold”, which is much cheaper as in a temporary medium like a battery. With technology like this is it possible to use solar energy to chill whatever during nights in large scale and by this to go 100% on solar/wind for chilling on large scale.

China sets up more than 650,000 solar panels a day

In just three months from April to June has China installed 18 Gigawatts (GW) solar energy. To express that in single solar panels; If we start with a solar panel that gives a power of 300 watts, it equals 60 million solar panels in just 92 days. This is 652,000 solar panels per day, 27,200 per hour and 452 per minute – every minute, around the clock.

Land area with solar to cover worlds total energy needs

The theoretical area of the small black dots is sufficient to supply the world’s total energy needs of 18 TW with solar power.

Solar areas defined by the dark disks could provide more than the world’s total primary energy demand (assuming a conversion efficiency of 8%). That is, all energy currently consumed, including heat, electricity, fossil fuels, etc., would be produced in the form of electricity by solar cells. The colors in the map show the local solar irradiance averaged over three years from 1991 to 1993 (24 hours a day) taking into account the cloud coverage available from weather satellites.

Español: Las areas solares definidas por los discos oscuros podrían suministrar más energía que el total de la demanda de energía primaria mundial (asumiendo una eficiencia de conversión de un 8%). Esto significa que toda la energía actualmente consumida, incluyendo calor, electricidad, combustibles fósiles, etc., podría ser producida en forma de electricidad por medio de células solares. Los colores del mapa muestran la irradiación local promediada durante tres años de 1991 a 1993 (24 horas al día) tomando en cuenta la cubierta de nubes mostrada por los satélites meteorológicos.
