The main components of an air-source heat pump are:

• a heat exchanger, over which outside air is blown, to extract the heat from the air
• a compressor, which acts like a refrigerator but in reverse and raises the temperature from the outside air
• a way to transfer the heat into a hot water tank or heating system.

An air source heat pump typically draws approximately 1/3 to 1/4 of the electricity of a standard heater for the same amount of heating, reducing utility bills. It has few moving parts, reducing maintenance requirements and may be used to heat water or cool as per user’s preference.

The tanks have a chrome finish outer casing for a perfect look and extra long service.

They are effective and reliable products designed to give trouble free operation in an economical and efficient package

Solar fridges/freezers are ideal for remote schools, hospitals, hotels, camps and for field offices as well as rural homes.

Prices for a complete solar fridge/freezer, solar panel(s), battery and charge controller range from KShs. 160,000 to KShs.190,000.

The unit comprises of a 20W solar panel, a 17AH sealed battery, 10 cables to connect mobile phones to the unit and 60 different pins to charge the mobile phones.

The unit retails at KShs. 25,000.

The 30W kit consists of a 30W solar panel, a 33AH sealed battery, 5 LED bulbs with 10M long cable and switch each, a universal mobile phone charger and a jack pin to connect to a small 6V radio.

It can also be used to charge 20 mobile phones or run a Kinyozi with three shaving machines the addition of a 375W inverter.

The complete unit retails for KShs. 25,000. The 375W inverter is extra and costs KShs. 7,000.

The solar table lamp lights for up to 4 hours once fully charged and retails for KShs. 1,200

The system consists of a heat collecting panel and an insulated water storage tank. During the day, the sun shines on the solar panel heating the water. This water rises into the tank because of the principle of thermosiphoning which also causes a displacement effect in the tank. The cold water inside the tank flows into the heat collecting panel to get heated and this process gets repeated until all the water gets heated up. This water is stored in the hot water tank for use later. (This water is available hot the following morning)

Did you know;

• Solar water heating is one of the most practical and proven technologies of utilizing the sun’s energy
• Has zero running costs, offering better value for money
• Is unaffected by power cuts
• Require minimal maintenance
• It taps a safe, clean Inexhaustible energy source

Solar energy helps protect the environment from pollution and damage that other heating can cause, but did you know that unless your solar hot water system is efficient and durable you could be paying unnecessary electric/wood booster costs.

Solar World offers a wide range of solar heating solutions no matter your climatic conditions or area you are leaving in. We have solar systems designed to meet the water conditions and your family’s usage.

Talk to our experts about your family needs and we can workout the best way to help you save up to 95% on water heating costs. Solar World also utilizes the evacuated tube technology for solar water heating systems, this is a well proven water heating technology.

Economic justification of solar water heating
Employing solar energy makes a great deal of economic sense. Research indicates that 50 – 80% of all household electricity bills are consumed by water heating.

Assuming an average electricity bill for a small household consuming 60 gallon of hot water per day; economic projections are as follows (for water heating per month).

Consumption (units)
Cost per unit
Other charges
Total cost per month     300
6.58/-
2,400/-
4,374/-

This translates to an average monthly water-heating bill of KShs 4,374 or KShs 52,488 per year.

A solar heating system of 60 gallon will cost approximately Kshs145,000. If one chooses to install this, it means that there will be a payback period of only two years and a seven months after which the system will effectively be earning the owner at least KShs 50,000 every year!

Why pay more when you could have your solar heater running on absolutely free energy from the sun?

Life Expectancy
Our systems have an expected lifespan of 20 years with minimal maintenance. Our guarantee on the system is 5 years.

For commercial/institutional applications, the system is configured after a site survey.

A standard solar lighting kit consists of:

1. A solar panel/module (mono or polycrystalline) to transform light energy from the sun into electricity
2. A solar deep cycle battery bank to store the power generated by the solar panel
3. A charge controller to protect the battery from over-charge and over discharge
4. An appropriate number of DC lights (fluorescent tubes or U-type energy saving lights)
5. Connecting cables and electrical accessories such as switches, sockets etc
6. An inverter unit incase of a need for AC power from the system

Solar electricity refers electrical current generated by certain surfaces called photovoltaic surfaces when exposed to sunshine. Light energy from the sun consists of energy particles called photons. When photons strike the special photovoltaic surface, they knock of electrons from the material and these electrons can be tapped and used to power lights and other equipment requiring electrical energy. The beauty with solar electricity technology is that it does not comprise of any moving parts and thus can generate electricity continuously for very long time periods.

It can also be used to charge 5 mobile phones  or run a Kinyozi with the addition of a small 150W inverter.  The complete unit retails for KShs. 9,500. The 150W inverter is extra and costs KShs. 3,500.

The Powerpack consists of a 5W solar panel, a 7AH sealed
battery, 2 LED bulbs with 10M long cable and switch, a cable
to charge mobile phones with 5 different pins and a jack pin
cable to connect to a small radio.

The complete unit retails  for KShs. 6,500 and is a
basic/beginners solar system.
