  • What is a solar water heater?
    A Solar Water Heater is a device which provides hot water for bathing, washing, cleaning, etc. using solar energy. It is generally installed at on the roof of a house or where sunlight is available and heats water during day time which is stored in an insulated storage tank for use when required including mornings.
  • How do solar water heaters work?
    A Solar Water Heater comprises of an array of solar collectors to collect solar energy and an insulated tank to store hot water. Both are connected to each other. During the day time, water in solar collectors gets heated and either pumped or flows automatically on thermosyphon principle to the storage tank. Hot water then stored in the tank can be used for various applications.
  • Does Mayu Solar Water Heaters work in any weather?
    Solar water heaters can operate in any weather. Performance varies depending, in part, on how much solar energy is available at the site. On cloudy days also, if it is for a day or two, you still get warm water as water gets heated due to diffused radiation available in the atmosphere. Kenya is lucky to have sunlight good sunlight for at least 300 days a year.
  • What types of solar water heater is suitable for my house?
    We choose the size and type of solar water heater to install based on several factors including the size of family, bathing habits, number of bathrooms, plumbing area, available space for installation, use of pressurized pumps, direction and availability of sunlight, etc. Mayu solar majorly deals with two types of solar water heaters – evacuated tube (heat pipe) collectors and flate plate collectors. Evacuated tube systems are more affordable than flat plate based systems and work very well in cold areas. Flat plate system do better in areas with hard water.
  • Are there any prerequisite before installing a solar water heater?
    A survey of your place will be made by Mayu Solar experts and a proper guideline will be provided to you.
  • Do I have to re-do plumbing at my house before installing a solar water heater?
    Generally not required. Minor changes may be required. Mayu Solar technicians will advise accordingly after conducting a site survey.
  • What is the cost of installing a Solar Water Heater in Kenya?
    Actually purchasing a Mayu Solar water heater should not be treated as an expense but rather as a cost. It is a very good investment that will lead to lots of future saving. It not only saves money but also the environment. The cost of a solar water heater depends on size and type of system installed. The most common system is 200 litres solar water heater which is sufficient for a family of 3-4 members. The cost, however, does not increase linearly with increase in capacity; rather it comes down proportionately as we go for higher capacity system.

  • Why should I install a solar water heater and how much can I save?
    A 200 litres per day capacity system suitable for 3-4 people can save up to 2,000 units of electricity in a year, depending on hot water used. Higher capacity systems will save higher amount of electricity besides reducing higher amount of gas emissions. Electricity is expensive and is not always available due to power blackout in many areas when required for heating water. Solar Water Heater, since it stores hot water in an insulated tank, provides water all the time when required.
  • How do I ensure that a quality solar water heater is installed in my house?
    There are many substandard solar water heaters currently being retailed in Kenya which fail shortly after installation. It is prudent to ensure that your solar water heater is supplied and installed by a company licensed and accredited by the energy regulatory commission (ERC). Mayu Solar is accredited by ERC and had installed more than a thousand solar water heaters in Kenya. We are so confident about our systems that we give our clients 7 years warranty on tank and tubes / plate and 2 years free service.
  • What is LED lighting?
    LED stands for Light Emitting Diode. This is light produced using a semiconductor in a process called electroluminescence. The process is much more efficient than what’s used by traditional incandescent lights and has a much longer lifespan. Its small size and relatively cooler operating temperature means that it can be used in shapes and forms that would have been impossible to light with traditional bulbs.
  • Are LED lights brighter?
    Not necessarily. Like any fixture, the output depends on how much wattage it takes in and how many lumens it produces (lumens are a measurement of light’s brightness). Because LEDs produce many more lumens per watt than incandescent or fluorescent bulbs, you can’t look at wattage alone. While most people can reference wattage for a classic incandescent bulb, the wattage and the amount of light produces with LEDs is drastically different. A good rule of thumb is that 1600 lumens equals about the same amount of light as a 100-watt incandescent bulb.
  • What is a Lumen? What’s the Difference Between it and a Watt?
    Lighting—it’s all about lumens. Lumens is now THE way to find out how bright a lighted bulb is. The lumens definition is: “a unit of luminous flux in the International System of Units, that is equal to the amount of light given out through a solid angle by a source of one candela intensity radiating equally in all directions.” In short…lumens equals brightness! And watts do not. Not that watts are bad, but they measure energy use, not light output. With new, energy-efficient LED technology, we can no longer rely upon wattage to indicate how bright a bulb is.
  • What are the benefits of replacing your ordinary bulbs with the LED?
    There are many benefits. Here is a list of a few: 1. An immediate reduction in your electricity bill. 2. Less heat. LED fixtures are extremely efficient converting electricity into light. 3. LED Bulbs last a very long time, typically 50,000 to 100,000 hours. 4. They are virtually indestructible. 5. They do not contain mercury or other hazardous materials 6. Highly recyclable – with no hazardous parts, you can easily reclaim most of the parts in an environmentally safe way.
  • How much money can you save when converting to LED?
    It all depends what you are converting. Incandescent to LED, fluorescent to LED, Metal Halide to LED.But it is not uncommon to see at least a 70%+ savings on your energy consumption.
  • What is CRI?
    CRI is Color Rendering Index. It is a measurement of the quality of light. Where as lumens is a measurement of the quantity of light, CRI is the measurement of quality. It is a scale between 0 and 100. 0 is bad, 100 is great. LED’s typically are in the 70-95 range. The higher the CRI, the more expensive the LED chip, and therefore the more expensive the product itself.
  • Are LEDs environmental friendly?
    LEDs are very environmental friendly. For starters, they use much less electricity than many other lighting products. This means that less electricity has to be produced to operate them, and resulting in lower emissions from power plants. Unlike CFLs, they contain no mercury. Because of their long life, they also reduce solid waste. If you replace an incandescent bulb with an LED, you will prevent fifty 1,000 hour incandescent bulbs from being thrown away.
