Engensa installs free panels to your home if 3.5kW system can be mounted
on your S, SE, or SW facing roof with pitch of 20-55 degrees. As a rule of a thumb we need unobstructed
almost South facing roof with about 30m2 (4m x 7.6m). We do not need to install panels on main residential object
if there is a nearby anciliatory object large enough. Roof must not be shaded and your house need to have EPC rating of D.
All of this will be assessed in a free no obligation survey.
How does the arrangement work?
Technically you rent the space above your roof to a trust that invests in solar systems for 25 years. Engensa installs
and maintains the system. The trust gets Feed-In Tariff payments while you can use all the electricity generated for
free and this represent the rent. After 25 years the system transfers into your ownership (it still has about 15 years of
life in it). During lease period all the costs associated with the system are paid by investors. There is no
administration fee or any other fee to the same effect. If your property qualifies, free means free.
- Feed-In Tariff fell from 43.1p to 14.4p. Free solar is dead.
Fiction. While feed in tariff has been lowerred a lot and not in a very subtle way,
prices of supplies have also fallen tremendously and installers learned
to be more efficient. Economy of scale make Engensa satisfied with lower profit margins.
Seeing stable returns from previous installations our investors
are satisfied with lower return on their investment as solar is not percieved
as very risky.
- Some solar panels can be up to 13% more efficient
Fact, but they can cost up to 59% more so their unconditional use may
not be economically justified! One would prefer them at the same price or
at a 10% premium while 50% higher costs are not justified. Just like a
worker that makes 10% more products at the same time as another. You may pay
him 10% more but you would not pay him 50% higher wage.
- Chinese solar panels are of lesser quality
Fiction, some of Chinese products are highly reliable and performing,
and they come with guaranties from international insurance companies,
and they are MCS approved so they must satisfy required industry standards.
Chinese participation has driven photovoltaic prices down rapidly, lowering
profit margins of US and EU manufacturers and installers, and Chinese are not
very liked in PV community for the same reason consumers should love them -
through economy of scale and improvements in production process they contributed
to lower prices for end user and society as a whole.
- UK government will run out of money to pay Feed-In Tariff obligations
Fiction, there is a mechanism in place where consumers (you) pay for
renewable energy on every energy bill (gas and electric) and this money
is used to pay Feed-In Tariff obligations. The scheme is designed so that
it is self financed. If more investors build solar, the charge for renewable
energy support on energy bill will rise to meet accepted obligations.
- Panels can be placed on North facing roof
Yes, in Australia. In UK they will perform 70% worse than panels facing South.
- Solar is just a quick fashion fad that won't last.
Fiction, UK plans to build 1.9 GWp of solar installations annualy by 2020 so this
means 15GWp of solar installations. If average solar installation were 4kWp we would
need 3.750.000 installations in about 3000 days or 1250 installations every day from
now to 2020. That is 5 MWp a day. Far above what all UK solar companies are installing now!
