Solar energy is the most sustainable source of energy for the future, as it does not pollute the environment and the sun is an infinite source of energy. Solar cells convert sunlight into electricity. This technique is known as photovoltaic conversion or simply PV (where ‘photo’ refers to light and ‘voltaic’ to voltage).
IN A SINGLE HOUR, THE SUN TRANSMITS MORE ENERGY TO THE EARTH’S SURFACE THAN THE WORLD USES IN A YEAR….
PV solar panels are a source of free, green and renewable energy that dramatically reduces your carbon footprint – and your energy bills. PVsolar panels are silent, require little or no maintenance, and generate electricity for a lifetime
At Battery World, we design, supply and install solar photovoltaic (PV) and solar thermal systems for homes and business across East Africa, helping more and more people discover the benefits of generating their own clean energy . We are experienced in working with all sectors, including commercial, residential, agriculture, public sector, contractors, architects, planners and community groups.
More importantly, we consistently receive excellent customer feedback and are especially proud that a third of our new customers are referrals
As the leader in solar PV installations, we understand that every installation is unique and we design, create and install solar PV systems which are suited to each individual needs. Battery World undertakes a survey to ascertain the suitability of your home/ business for a solar pv installation. As part of this survey, our professionals will give you advice and recommendations.
We will send you a written quotation: including a detailed breakdown of the costs involved, our guarantees and warranties
Our installation management team manages and organizes the installation to suit you. We ensure that each and every customer is kept up to date with the progress of their installation from start to finish. Our installations are completed by our very own in-house highly skilled professional installation teams. The installation of solar panels typically takes 1 or 2 days to complete.

Any electricity produced by your Solar PV system is used in your home. The reason for this is due to your current coming off your roof is at a slightly higher voltage than that coming into your home.
SOLAR POWER SYSTEMS
Solar power is energy from the sun that is converted into thermal or electrical energy.
Solar energy is the cleanest and most abundant renewable energy source available. Modern technology can harness this energy for a variety of uses, including generating electricity, providing light or a comfortable interior environment, and heating water for domestic, commercial, or industrial use.
1.5 billion People worldwide live without access to electricity. For people without access to an electrical grid, solar energy is the most cost-effective source of electricity as it provides clean energy to select regions and creates new opportunities.
While the start-up costs of solar equipment can be higher than generators, the long term operating costs are very small since there is no fuel to buy and little maintenance to carry out. With a battery storage excess generated electricity can be stored.
In its simplest form, all that is required for a solar power system is a panel to collect the sun’s energy and a battery to store that energy. When the sun is shining, the panel will produce a voltage higher than that of the battery, causing the battery to be charged. Most panels will include a blocking diode (an electrical component that will only allow electricity to pass in one direction) ensuring that the battery does not discharge through the panel when the sun is not shining.
A connection can be taken from the battery to provide a low voltage direct current for use.
This system could be used to power a small piece of equipment in a location where there is no power.
There is however need for improvement. With the above setup, if more power is being produced than is used, the battery will be charged to a voltage that is high enough to damage the battery. Also, if more power is being used than is being generated, the battery voltage will drop to a level where again, damage reducing the life of the battery will caused.
This system needs refining by the addition of a charge controller as shown in the circuit below.
The charge controller simply connects between the panel and the battery where it monitors and controls the current flow.
In its simplest form, the charge controller will stop the current flow from the panel if the battery voltage exceeds a pre-set level.
Most controllers will also have a connection from which current may be drawn for lighting or powering equipment. This current flow will be stopped by the controller if the battery voltage drops below a pre-set level.
In many cases however, the power requirement is for a supply that is similar to “mains” electricity ie, 120 or 230 volts AC (alternating current).
To meet his requirement, an inverter is required.
Photovoltaic (Solar Electric)
Photovoltaic (PV) devices generate electricity directly from sunlight via an electronic process that occurs naturally in certain types of material, called semiconductors. Electrons in these materials are freed by solar energy and can be induced to travel through an electrical circuit, powering electrical devices or sending electricity to the grid.
PV devices can be used to power anything from small electronics such as calculators and road signs up to homes and large commercial businesses.
