With ever-increasing energy bills, more people are considering the option of investing in a photovoltaic (PV) solar panel system in order to generate their own power.

Solar systems of the 'thermosiphon'-type, where the water tank is mounted horizontally above 1 or 2 solar panels, have become a familiar sight on many Algarve rooftops. They are a time-proven technology, but in some situations can look unsightly.

Whether your water is from mains supply or a borehole it contains minerals and chemicals that, over time, corrode unprotected metal areas and components in your solar system's water tank.

Solar hot water: A solar system for domestic hot water is one of the most worthwhile investments for your home. A typical house with gas water heating may incur bills of €60-€70 per month. The cost of a 200-litre thermosiphon-type solar system will be recouped in 3-4 years and provide FREE hot water for many years after.
Integrated Solar Heating System

Solar systems are commonly used to provide domestic hot water, while larger arrays of panels are used to heat pools. In some situations, solar systems can also be used for underfloor heating. For this project we were required to devise and install a system which integrates all three applications.
Solar systems: Thermal vs. Photovoltaic (PV)

A commonly-asked question is: “What kind of solar system is best for supplying domestic hot water? One with thermal solar panels, which heat the water directly? Or one using photovoltaic panels, which generate electricity to power a heating system?”
To consider this, the following comparison is useful - If a standard 3kw electric immersion heater takes around 5 hours to heat a 130-litre water tank from 10°C to 60°C then a THERMAL solar system needs two panels to achieve the same, requiring 4m² roof space and logically a PHOTOVOLTAIC system needs around twelve 230W PV panels (2.76 peak output) to achieve the same, requiring around 24m² roof space.
Assessing Your Energy Saving Solutions

When considering energy-saving solutions – a solar hot water system, a photovoltaic (PV) system, a heat pump - you should aim for a return-on-investment of 5-7 years. It's wise to invest in a good brand – quality is key because you are looking for a 25-year lifespan.
For example: you want to replace your gas water heating with a thermal solar system. Let's assume your gas bills are around €50-€70 per month, €600-€840 annually, therefore €3000-€4200 over 5-7 years. A quality 2-panel solar system can be installed for around this sum, providing free hot water for many years after the investment has been recovered.
