BASICS
All energy what we can get from all available fossil oil sources in our planet is equal to the sun’s energy transmitted to the Earth in 1,5 days. All energy forecasts agree that by 2025 solar energy will be the leading source of energy in our planet.
Solar panels (PV) photovoltaic modules generate electricity from sunlight and provide clean power for homes, communities and businesses. Today the photovoltaic systems are mostly implemented in the form of solar panel. When installing a solar panel on the roof of a residential house there is significant installation cost, the design of the house is ruined, and a supporting structure must be implemented with the disruption of the water sealing capability of the roof.
PvROOF solar tile system is a revolution in solar technology. It is a roof tile with integrated solar cells. The product combines the solar photovoltaic panel and the ordinary ceramic roof tile in one.
The PvROOF solar tile remarkably eliminate the disadvantages of the original products. No installation cost of the panels, the design of the roof remains the same, the tiles have better heat insulation and considerably lower weight.
The tiles are produced in identical shape and colour of the ordinary ceramic tiles. This provides modularity use on residential house roofs and flexibility to end-user in system enlargement.
PvROOF solar tile system is patented in the United States.
SOLAR SYSTEMS IN 2017
Active solar techniques include the use of photovoltaic systems, concentrated solar power and solar water heating to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favourable thermal mass or light-dispersing properties, and designing spaces that naturally circulate air.
PHOTOVOLTAIC SYSTEM
Photovoltaics is the direct conversion of light into electricity at the atomic level. Some materials exhibit a property known as the photoelectric effect that causes them to absorb photons of light and release electrons. When these free electrons are captured, an electric current result that can be used as electricity.
In 1905, Albert Einstein described the nature of light and the photoelectric effect on which photovoltaic technology is based, for which he later won a Nobel prize in physics. The first photovoltaic module was built by Bell Laboratories in 1954. It was billed as a solar battery and was mostly just a curiosity as it was too expensive to gain widespread use. In the 1960s, the space industry began to make the first serious use of the technology to provide power aboard spacecraft. Through the space programs, the technology advanced, its reliability was established, and the cost began to decline.
Electricity is being produced cleanly and silently without any spinoff. The photovoltaic system works automatically and requires no maintenance. The solar cell produces directly direct current which can be upgraded to alternating current by using an inverter to the standard 110/220 V.
The ordinary solar panels are:
-
in rectangular panels of 15 SQM with a net weight of 20 Kg (44 lbs)
-
depending on manufacturer it can produce 200Wp per panel
-
it requires an aluminium holding frame
-
it is necessary to open the roof and disrupt its water sealing capability
-
the implementation is only carried out by a qualified technician
-
the cost of the implementation is high compared to panel price
