There has never been a better time to invest, due to high gas & electricity prices, will continue to grow. As the cost of energy increases, so too will the cost of materials, therefore it is more beneficial to make the change sooner rather than later.

  • Affordable clean, green, safe energy
  • Now is the time to invest your money productively and get the return from it that you would expect.
  • Be self sufficient for your electricity needs, any surplus sold back to the grid
  • Simple Installation process
  • No planning permission unless you are in a conservation area or listed building
  • It works all year round
  • You can decide what size system you would like according to your budget
  • Adds value to your property
  • The systems are silent in operation
  • Life expectancy approximately 30+ years
  • No moving parts, so do not require any maintenance

Let's make our planet more clean

Researchers believe, by 2050 the world's main source of electricity will likely be the sun.

A kW is a thousand watts and a unit of power. A kWh is the amount of energy used (or in our case generated) when a kW of power works for one hour.

We use Watts (W), kilowatts (kW) and kilowatt peak (kWp) to measure power when sizing a system to ensure that all of the different components will work efficiently and safely together when connected.

We use kilowatt hour (kWh) and kilowatt hours (kWhrs) to measure how much usable power will be generated and or available for export/sale. Conventional electricity bills are measured and payable based on kWhrs, Feed in Tariff payments are also based on kWhrs.

Accurate kWh estimates can be prepared in advance of an installation based on historical solar radiation data combined with the characteristics of the installation and the location. In Sri Lanka,we typically see that for every 1kWp of installed PV you get a return of between 1400 and 1700 kwhrs of electricity per year. The better the system design in relation to it’s location the greater the kWhrs return will be.

If you would like more information about the various components found in both on-grid and off-grid solar PV systems; we have written an article where we describe the different components and the functions they carry out here: Solar PV System Components

Daylight hits the photovoltaic cells and is converted to electricity. The inverter converts the electricity from direct current (dc) to alternating current (ac) which can either integrate with existing power systems or charge batteries.

Further information about the types of solar PV system and an overview of how they work can be found here: Types of Solar Photovoltaic (PV) System.

Connecting a PV system to the distribution network is arranged by the installer working with the Distribution Network Operator (DNO). The DNOs are the power companies that run the power distribution networks There are two engineering recommendations (G83/1 & G59/1) that are followed by both the installer and the DNO to ensure that the solar PV system will integrate safely with the national grid.

Solar PV systems under 16A per phase (i.e under 3.68kWp) come under engineering recommendation G.83/1. Solar PV systems installed under G.83/1 can be installed without prior notice to the DNO, with the DNO being informed afterwards

Solar PV Systems over 16A per phase will need to consult the DNO before the PV system is connected to ensure that the distribution network can handle the extra power being provided. Depending on the system size and the DNO’s preferences, larger systems may be installed either under G.83/1 or G.59/1.

If the building is connected to the National Grid then your system will not need batteries as any excess energy can be sold to and fed into the grid. During the winter this process can be reversed and the grid can feed your buildings’ electricity system, you will essentially use the grid as your energy store.

If mains electricity is not available or you want to store electricity locally you can use batteries. Batteries can also be integrated into hybrid grid tie / battery systems as a backup, protecting against mains power cuts.

shading has a disproportionate affect on a systems performance. This is because the cell with the lowest illumination determines the operating current of the series string in which it is connected. This is one of the areas that must be covered in a survey carried out before the installation.

Modern arrays can bypass the effected diodes to minimise shade effects; but these effects must still be considered as system yields (kWhrs) as well as other factors will be affected.

Solar photovoltaic (PV) systems are silent in operation, have no moving parts and require minimal maintenance. At low tilts (less than 16°) horizontal glazing bars can sometimes trap debris which could lead to shading of part of the array. The design of the system should aim to minimise uneven soiling. Panels are pretty robust so if they get dirty rub off the dirt with a damp cloth or blast them with a hose (no detergent).Bird nuisance in particular roosting under panels has become a problem in certain areas and as a result we have developed a system to prevent this happening, please refer to our maintenance page.

The basic solar PV panel (interconnected, enclosed panel of PV cells) has no moving parts and can last more than 50 years. Most solar PV panels are provided with 25 year power guarantees direct from the manufacturer as standard.

As well as solar PV panels a DC to AC inverter is needed to supply power to a property. The current lifetime estimates for solar PV DC/AC inverters is from 15-20 years. Although some manufacturers offer warranty extensions up to 25 years.

Solar electricity is green, renewable energy and doesn’t release any harmful carbon dioxide (CO2) or other pollutants. A typical domestic home PV system could save over 1 tonne of CO2 per year – that’s more than 30 tonnes over its lifetime. Cut your electricity bills: sunlight is free, so once you’ve paid for the initial installation your electricity costs will be greatly reduced. A typical domestic home PV system can produce around 50% of the electricity a household uses in a year. Sell electricity back to the Grid: if your system is producing more electricity than you need, or when you can’t use it, someone else can use it – and you could make a bit of money.

Our Products

Solar Panels (100% German Panels)

Jurawatt German started the development of solar panels for more than 30 years and through constant R & D continued to develop high best products with excellent reliability levels. Desert solar modules is innovative potential and extensive know-how product from Juarwatt for the higher temperature region with maximum yield. Jurawatt’s Desert Modules are ideal for Sri Lanka’s tropical climate where temperatures peak at almost 31 degrees centigrade . This heat, plus the country’s high levels of humidity and heavy monsoon rainfall do not pose extreme challenges to module technology.

Desert Technology: Modules made for Extremes

solanra.com / #products

Standard panels are made for regions with a moderate climate. All promises for performance and durability are based on moderate weather conditions;. Many research companies (e. g. IRESEN in Morocco) have conducted extensive tests with standard panels in desert regions or in regions with temperature higher than those found in central Europe: Most panels lose much of their nominal power after 10 years and only some of panels continue to work for more than 15 years at 80% capacity. But Juarawatt Desert Jurawatt now produces and sells these special DESERT panels all over the world. Facts about the new DESERT panels from Jurawatt can be found here.
