Power from the Sun.
Generating power for your home is not only more sustainable, it makes you independent from the grid. Power cuts won’t exist if you have a Madison Solar home system. Madison has any number of solutions to suit your needs.
Solar Day and Night
Your home power demands fluctuate during the day and night. Excess power produced during the day is stored in a battery for power demands at night. This makes your solar power available to you when you need it, even at night.
How it Works
Our Home Solar installation consists of a solar panel array, a Hybrid UPS inverter and a battery bank to store all the solar energy yield for use at a later time.
Solar Panel Array
Installed on your roof, the solar panels convert Sunlight into electricity. Typically panels are between 180-305 Watts.
Solar Charge Controller
A Victron MPPT solar charge controller takes care of the right amount of DC solar energy produced, alternatively a Fronius single phase grid Inverter with build in MPPT can be used to produce AC power for direct use and/or feed back into the grid.
This is your storage of excess sunlight that you did not use during the day or power from the grid when it’s available.
The Hybrid Inverter
Converts the DC electricity from solar panels or the battery into AC current used by your home appliances, lights and other devices.
The Grid Tied Solar Inverter
Works without a battery bank and usually includes one or several build in MPP tracker. These transformerless inverters can be used for self consumption or feed back power into the national grid. Fronius grid tied inverters are available as string inverters, single and split phase from 3KW to 27KW.
- From Grid 17%
- From Battery 47%
- From Solar 36%
- From Genset 0%
Hybrid Grid System
In Zimbabwe our hybrid grid connect system means your property is still connected to the mains power supply with a battery bank for power cuts. A hybrid grid connect installation ensures you have the electricity you need, whenever you need it – automatically and regardless of conditions. This system also works in remote areas where there is no mains supply.
Let’s Prioritize solar yield in a DC-coupled system to ensure fast financial return on your Investment by cutting down on your ZESA bill
Victron MultiPlus/Quattro, powered by the grid, solar charger, solar batteries, AC loads and optionally also DC loads.
Older Victron Inverters use the virtual switch (VS) to enable ignore the AC input, based on battery voltage, and optionally also on electrical power being drawn by the AC loads.
Newer Victron Inverters use either the VS or the new ESS (Energy Storage System) assistant. It will only charge the batteries from the grid if needed to preserve battery health, and leave the rest for the solar chargers. The mechanism preserving battery health is called sustain.
This assistant has more relevant optional features:
• load shedding
• feeding back dc-coupled solar power to the grid
• periodic equalisation/destratification charge
Both solutions aim at making full use of solar power generated by your system while keeping your batteries fully charged for possible night grid failures or load shedding. Once legal and technically possible in Zimbabwe, Victron Inverters through Assistants and smart build in software are able and prepared to feed power back into the grid which will ideally generate an income for you on excess solar power produced by your array.
Victron an Fronius have partnered up to integrate each other’s systems and can be seamlessly added to any grid tied or off grid solar system, allowing the most advanced and efficient interaction with incredible flexibility to suit any of your needs.
The ultimate goal for most our customers is, besides the convenience of having a reliable and professional 24/7 Solar power backup system, a financial return on their investment. Here is how it works and how we will help you to achieve it as soon as possible…………Read more down below.
Zimbabwe’s current power tariff is around about 0,10 – 0,18 $ per KWh. A price increase of about 25% is expected in the very near future but let’s work with 10cts for now. Our larger solar powered systems with a solar array of 8-10KVA, yield an average of 35-40 KWh of solar power a day, depending on time of year and system settings. An average of 35-40 KWh daily accumulates to 1 MW or 1000 KWh of generated solar power a month. 1MW of energy would cost you 100$ if drawn from the national grid (ZESA), assuming the grid is alive all the time conveniently supplying you with all the power needed. A solar array of 8-10 KVA output will cost you in the region of 10.000 – 12.000 $ and it will take 8 – 10 years at current power tariff costs to break even. That may seem like a long time but the sun is unlike our grid reliable and will supply you sufficiently with the power needed during that time after which it will keep producing solar power for another 15 – 20 years to come, free of any charge and might generate another 25.000$ worth of free and sustainable clean energy. Solar panels of good quality have a manufacturer warranty of 25+ years. With smart settings on your professional Victron or Fronius inverter, we will make sure you prioritize solar energy even if the grid is alive and maximise your future profits and return at incredible convenience as you will have power from the sun 24/7 (Batteries for night storage needed) As mentioned earlier, Zimbabwe is expecting the next round of tariff increases which have not yet been considered in the above model. Electrical power is a commodity in high demand and as an example cost as much as 45cts per KWh in Europe already. South Africa has in fact just had an increase of 25% and since Zimbabwe is importing power from surrounding countries to supply part of its demand, has no other option then keep up with costs and pass on higher electricity costs to its customers. So, get in touch today to get your quotation and don’t wait until the new tariff sets new record benchmarks.
As a complimentary service to our customers, our engineers can remotely monitor your system and apply system changes from our HQ for your piece of mind and most efficient functionality. All free of charge.
A feed in tariff is expected to be implemented by ZERA towards the end of this year.

How much power does your home use?
1,600 Watt Hours per Day
Understanding Watts: A Quick Guide
It’s important to understand how your power is used
Watts are Like Kms-per-Hour
Let’s start with that 40-watt lightbulb. Power is a measure of the rate at which energy flows, and in electrical systems it is measured in watts (W). Watts are basically the kilometers-per-hour measurement of the electrical world, they tell you how fast the electrons are speeding down the road. For those who are keeping track, one watt is equivalent to electricity flowing at a rate of one joule per second in the metric system, which is also equivalent to 3.4 Btus per hour. A 40-watt lightbulb will consume electricity at a rate of 40 watts.
kWh are like the Km you have travelled
When you get your ZESA bill, the electricity you’ve used is measured in kilowatt-hours (kWh). While a watt is a measure of power, a kWh is a measure of energy. If you run a 40-watt lightbulb for one hour, you’ve used 40 watt-hours, or 0.04 kilowatt-hours, since a kWh is 1,000 watt-hours. In other words, 0.04 kWh is the amount of energy you need to run a lightbulb for an hour. If you travel 100 km in a car, you could drive at 10km/h or 100 km/h, the difference is the arrival time. Energy is similar. The more watts used, the quicker you will be using Kilowatt hours.
Your own Power Station
Now you understand the basics, Imagine you have your own power station (A Madison Hybrid Solar System), and every day you get a delivery of power (Sunshine.) You can now run your appliances using the free energy you get every day. Pretty soon your power station will pay for itself. You are less reliant on the grid and are helping reduce the burden on the current infrastructure. So not only do you get a sustainable power source that reduces emissions, you get the convenience of a system that is silent and seamless. That’s priceless!
Ways to Reduce Your Power Consumption at Home
Cook On Gas
The electric hob and oven use electric elements that consume large amount of electricity in order to cook your food. Many Zimbabweans are turning to LPG as a fuel for cooking. The savings are beneficial and many find the changeover easy to do. When you decide to get a solar system from Madison, we recommend this change to all our customers as it reduces the size of the system you need to buy to power your home.
Goodbye Electric Kettle
An electric kettle is a huge power hog. The high wattage of electric kettle elements is a huge drain on your inverter battery and is easily replaced with a whistling kettle on your gas hob. Often overlooked in the home, the electric kettle is a very easy to live without replacement with a whistling kettle will save you power bills and extend the capacity of your hybrid solar system to power other appliances.
Invented in 1892, the vacuum flask keeps whatever you put in it hotter or cooler for longer. In an energy conscious home, keeping the excess hot water in a flask for that cup of tea a little later. It’s a satisfying feeling to have saved that gas, as well as a huge time saver. It’s highly likely you have this household item already so there is no outlay, making it easy to save energy today.
LED light bulbs are more affordable than ever. Easily halve your consumption by making the transition. LED is far superior to energy saving bulbs in service life and watts used. Don’t wait another moment. Replace any blown bulbs to the LED equivalent. If you are looking at one of our systems, then this is an excellent place to start. We advise all our clients go LED to reduce the size of the inverter needed.
Frequently Asked Questions
Can I Just Buy an Inverter and Batteries?
Absolutely, we have many clients who start their solar journey with an inverter and batteries only. The reason we get many of them adding solar panels later is simple, the sun charges up your batteries during the day and you get a return on investment by producing free power from the sun. Eventually you can be producing 100% free energy.
How long does it take to install?
Generally our average install time is 3 days. Larger or more complex installations can be longer. We can usually do the work in segments so the solar panels are installed and then the inverter battery installation is done. Madison is also able to structure and install to suit your schedule.
What size do I need?
This is very specific to your home’s needs and we prefer to do a site evaluation to advise you correctly on the setup needed. A 3 kva unit will be suitable for a smaller home. Our 5 kva system is most often requested for the average user and larger homes will use a 10 kva unit. Please use our contact form to book a visit. For larger more complex systems our engineers install a data-logger measuring your consumption precisely, recording several 24 hour cycles do design a customized system that fits you and your needs perfectly.
What can I do to reduce the size of the system needed?
The best way to reduce the size requirement is to reduce usage. We advise all our clients to make these considerations before we size a system:
- Can you change to LED lighting throughout your home?
- Can you eliminate use of electric elements such as water heaters and ovens as well as kettles?
- Are you able to shift your load requirements to daylight hours closer to solar noon?
Considerations like cooking on gas and heating water via solar geysers or gas result in lowering the overall size of the system you require or extending the battery life-cycle.
