Solar kits in Madrid: complete solutions for solar thermal and photovoltaic
Selection, supply and installation of solar sets according to property needs. Before contracting, components, compatibility, included work and proposal price are identified.
A solar kit is a preconfigured solution in which all components —collector, accumulator, pump, control unit, and accessories— have been selected by the manufacturer or installer to work together and ensure optimal performance. The main advantage over custom systems is the elimination of incompatibilities between components from different brands, the simplification of the installation process, and, in many cases, the reduction of the total cost as they consist of standardized sets. At Uniclima, we install turnkey kits: we take care of the selection, supply, installation, and commissioning.
The types of kits we usually install are three. The DHW solar kit (1-3 flat collectors + 150-300 L storage tank + solar group + differential control board) is the most demanded solution for households of 2-6 people who want to reduce hot water expenses by up to 70% annually. The solar kit for DHW+heating add a larger capacity storage tank (300-500 L) or a biomass buffer tank with a double coil to also connect the underfloor heating circuit or fan-coils. The basic photovoltaic kit (2-4 panels of 400 Wp + single-phase inverter of 1.5-3 kW + mounting structure) is ideal for homes or premises that want to start photovoltaic self-consumption with a moderate investment and the possibility of expanding later.
The installation process at Uniclima includes:
- Pre-technical visit to assess roof, orientation, and consumption: confirm its scope and cost before scheduling.
- Supply of the complete kit with all components certified (Solar Keymark for thermal, CE for photovoltaic).
- Installation in a single day in most basic DHW kits (2 collectors + 200 L accumulator on accessible roof).
- User trainingWe explain the operation of the control board, the screen parameters, and the indicators of correct functioning before concluding the service.
Frequently Asked Questions
Which solar kit is most suitable for a home without natural gas?
For a home without gas that uses electricity as its only energy source, the most cost-effective combination is a solar thermal domestic hot water kit (2 flat collectors + 200-250 L accumulator) along with a basic photovoltaic kit. The solar thermal system reduces the electric consumption of the water heater or storage water heater by up to 70%, and the photovoltaic system covers the remaining energy needs of the home. If the home also heats with a heat pump or electric radiators, adding a third collector and expanding the accumulator to 300 L allows for extended support for heating during the transition months.
How long does it take to install a basic DHW solar kit?
A standard solar DHW kit with 2 flat collectors and a 200-liter accumulator is installed in 6-8 hours by a team of 2 technicians, including the assembly of the structure on the roof, the hydraulic connection to the existing DHW circuit, the charging of the antifreeze fluid, and the commissioning of the control unit. More complex installations (3 collectors, difficult-to-access roof, bimasa accumulator for heating support) may require 2 days. The delivery of the materials takes between 3 and 7 working days from the acceptance of the budget.
