Making your home energy efficient
Solar/Wind Hybrid SystemSolar Water Heater
Solar and Wind Energy is becoming an appealing energy source worldwide.
Many people find a,rac/ve the idea of powering their homes or small business using a renewable energy system.
This makes sense in terms of reducing energy expenses by becoming independent from power providers, but as well as demonstra/ng a Eco-‐Friendly way of living.
Solar/Wind Hybrid System
Recent technological advancements, made possible the combina/on of wind and solar energy with the development of hybrid systems.
With these systems, implemen/ng Solar/Wind energy into most homes, has become rela/ve easy.
Overview
The combina6on of renewable resources has many benefits. The main are:
➡ Reduces the energy expenses of the house.
➡ Ensures an increased energy produc6on and a consistent power supply.
➡ Solar/Wind Hybrid System requires less space than previous systems.
➡ Eco-‐Friendly.
Main Benefits
Solar/Wind Hybrid systems are developed with the natural con6nuous change of the weather condi6ons in mind.
Usually sun and wind are not high at the same 6me. Combining Solar Panels with Wind Turbines, we can maximize the energy produc6on, by gathering and conver6ng power from both these 2 sources.
The use of a baLery system aids to provide a storage unit for the produced energy, that will be used under periods of energy shortage.
This way, we can ensure a non-‐intermiLent power supply during all the year, independent of the weather condi6ons.
How it works
A complete stand-‐alone power system requires the purchase of the following equipment:-‐ Photovoltaic Array (Solar Panels)-‐ Wind Turbines-‐ BaLeries-‐ Charge Controller-‐ Power Condi6oning Equipment -‐ Inverter-‐ Safety Equipment-‐ Metering/Monitoring
Op6onally, a stand-‐alone system can include either an engine-‐generator or micro-‐hydropower resources, to generate energy when solar and wind energy is not enough.
Equipment
A Photovoltaic array is an arrangement of mul6ple photovoltaic modules (solar panels), designed in such a way to collect the solar radia6on and convert it into electricity.
PV Array
The number of the panels determines the total electric power a system is capable to generate.
A small PV system is capable to provide enough power for the average needs of a house.
Solar Panels can be mounted on the ground or on the roofs.
!
A wind turbine, is a device that converts the kine6c energy from the wind into electric power.
Wind Turbines have a long technological history, that leaded to today’s wide range of wind turbines types.
Wind Turbine
!
In stand-‐alone energy systems for homes, small to medium size turbines are used as a complimentary generator to contribute to the domes6c power needs.
BaLeries store the generated electricity for use when the system is not able to produce (e.g. cloudy days, nights with no wind etc).
BaGeries
They usually have a life-‐cycle of 5-‐10 years and can be replaced when they lose their recharging ability.
The number of baLeries is depending on the actual needs and the climate condi6on at the loca6on of the installa6on.
BaLeries should not be located in living areas or near other electronics. It’s good to be placed in a separate room, with easy access for maintenance and replacement.
This device is used to control the flow of the electric power from the various sources to the baLeries and the home equipment.
Hybrid Charge Controller
!
Controller is detec6ng and op6mizing the electricity flow among the electric devices and the baLeries, based on the charging state of the baLeries, the current produced energy and the power requirements of the other devices.
Modern Controllers are able to re-‐act on the changing condi6ons and for example automate the start of an engine-‐generator in case of energy shortage, or control the charging cycle of the baLeries, something that can extend the baLery’s life6me.
Most electrical devices and equipment run on AC (alterna6ng current) Electricity. At the other hand, renewable energy technology produces and delivers DC (direct current) Electricity.
Power CondiIoning Equipment
!
In order to run AC devices, the DC electricity must be converted to AC. An inverter is such a device.
Sensi6ve electronic equipment like computers, televisions etc, require a consistent voltage and a smooth sine wave profile of electric power.
Inverters and other power condi6oning equipment are used to equalize the requirements between the devices connected to the home circuit and the power provided by the system.
It is always important to enhance the safety of an electric system, in order to protect the system itself against damages, but also people from harming.
The main dangers are during storms with lightening events, power surges, short-‐circuits events, devices malfunc6on etc.
Main protec6on against such hazards includes:
-‐ Safety Disconnects: Automa6c/Manual safety disconnects to protect the system or human, during accidents or maintenance.
-‐ Grounding: Power generators and electric devices need to be grounded.
-‐ Surge Protec6on.
Safety Equipment
Devices to meter and monitor the power consumed, the charging level of baLeries, the baLeries voltage etc.
Metering & Monitoring
The exact type of equipment and the number of units you are going to need to power your home of office, is depending on what you want your system to do.
The simplest system is to directly connect the power generated by the system to your home equipment for immediate use.
But if you want to also store the excess of the generated power, then you are going to need baLeries, charging controllers etc.
Please do not hesitate to contact us with the requirements of your installa6on and we will plan for you the right solu6on.

Energy Saving DataHow many energy can be saved by a solar water heater
For a 3 person houseElectricity Heater- 3 persons use about 150L hot water every day- Electricity heater needs about 15KW/H to heat 500L from 20° C to 50°C.- It needs 1620KW/H every year to supply hot water.
Solar Water Heater- It uses only Sunshine to heat water.- It has a 15 years lifespan.- This means that a Solar Water Heater can save about 24300KW/H in its lifecycle.
For a 50 rooms hotelElectricity Heater- A standard room needs about 100L hot water per day.- Electricity heater needs about 15KW/H to heat 500L from 20° C to 50°C.- We need 54750KW/H every year to supply hot water to 50 rooms.
Solar Water Heater- It uses only Sunshine to heat water.- It has a 15 years lifespan.- This means that a Solar Water Heater can save about 821250KW/H in its lifecycle for a Hotel with 50 rooms.
