Our products - solar heat collectors
Only the best is good enough
By many years of experience we at Solar Energy Mallorca know only the best is good enough. Solar heat collectors that look attractive and seem to be cheap at first sight may be very expensive too soon when they fail and need to be exchanged. For this reason we only trust in products that have proven high quality in many years of reliable function and are approved by leading technical authorities.
All solar heat collectors, solar heat centrals and other components made by german market leader SOLVIS meet highest standards both in efficiency and long term funtionality. Solvis has been rewarded many times for best possible technical solutions and consistent quality standards at highest level. Enjoy the good feeling of being shure to get the best possible state of the art technic at any time.
Flat compact solar heat collector SolvisCala
The SolvisCala is a high performance state of the art solar heat collector in a compact room saving design.
- measures 1.92 x 1.14 meters
- 60 millimeter heat insulation layer keeps all heat inside
- top-side hardened high transparency solar safety glas
- units are tested absolutely long term weatherproof
Large flat compact solar heat collector Solvis Fera
Where more solar heat power is needed larger heat collector units give several advantages like
- less assembly and installation time
- reduced heat loss at outer edges
- reduced number of connecting tubes
- less framing material for outer edges
Reasons enough to recommend SolvisFera solar heat collectors ranging from 5.6 to 8.4 square meters. Like SolvisCala the SolvisFera solar heat collectors feature
- 60 millimeter heat insulation layer keeps all heat inside
- top-side hardened high transparency solar safety glas
- units are tested absolutely long term weatherproof
Profit from Solvis experience in making solar heat collectors since 1988. In total they produced more than 300 000 square meters of solar heat collectors.
Advantages of Solvis made solar heat collectors in detail
- corrosion and weather proof aluminium alloy frames
- top-side hardened high transparency 3,2 mm solar safety glass, transmission 91%
- slim design only 105 mm
- full area surface optimized aluminium heat absorber
- high selective durable and environmentally friendly coating
- heat absorption 94%
- standstill temperature safety 250 degrees celsius
- high efficiency heat insulation, 60 millimeters insulation layer
- solid steel case
- small heat absorber volume gives high stand still safety
New heat absorber design boosts heat collectors performance
The solar heat collectors SolvisCala und SolvisFera contain heat absorbers made of high selectivity coated aluminium alloy and a laser welded assembly of densely packed copper tubes.
1 0,5 mm high selectivity mirothermŽ coated aluminium solar heat absorber
2 wide high efficiency laser welding
3 copper tube
More welding points than before and placing the copper tubes on the heat absorbers rear side result in better mechanical solidity and improved heat conduction. The entire heat absorbers top side is now heat by the sun. Compared to the former model laser welding and denser packing of the copper tubes result in a significantly improved total efficiency of Solvis made solar heat collectors.
The SolvisCala and SolvisFera solar heat collectors yearly solar heat harvest ranks on top of all available flat solar heat collectors. This makes them a first choice in solar heating and drinking water in particular when combined with a solar heat central of the same quality class like the SolvisMax. Solvis compact solar heat collectors are suitable for homes and public buildings as well as for restaurants and hotels. Who ever picks this choice will save serious amounts of money in the long run.
