Solar Suitability
- How suitable is the climate in the country for solar electricity

+3

May 6th 2014The sun provides a tremendous resource for generating clean and sustainable electricity without toxic pollution or global warming emissions.

The potential environmental impacts associated with solar power — land use and habitat loss, water use, and the use of hazardous materials in manufacturing — can vary greatly depending on the technology, which includes two broad categories: photovoltaic (PV) solar cells or concentrating solar thermal plants (CSP).

The scale of the system — ranging from small, distributed rooftop PV arrays to large utility-scale PV and CSP projects — also plays a significant role in the level of environmental impact.

For more on solar power technologies, see How Solar Energy Works.
For more on the benefits of solar power and other renewable energy technologies, see Benefits of Renewable Energy Use.
Land Use
 Depending on their location, larger utility-scale solar facilities can raise concerns about land degradation and habitat loss. Total land area requirements varies depending on the technology, the topography of the site, and the intensity of the solar resource. Estimates for utility-scale PV systems range from 3.5 to 10 acres per megawatt, while estimates for CSP facilities are between 4 and 16.5 acres per megawatt.

Unlike wind facilities, there is less opportunity for solar projects to share land with agricultural uses. However, land impacts from utility-scale solar systems can be minimized by siting them at lower-quality locations such as brownfields, abandoned mining land, or existing transportation and transmission corridors [1, 2]. Smaller scale solar PV arrays, which can be built on homes or commercial buildings, also have minimal land use impact.

Aug 3rd 2017Over the last two decades, the cost of solar energy systems has come down more than seven-fold. As the demand for solar power systems continues to rise and manufacturing volume increases, costs are further decreasing: from 2006 to 2016, the average cost of a system dropped from $9/watt to approximately $4/watt when professionally installed (source: NREL report) or $2/watt self-installed.

That’s great news for DIYers. By saving on installation costs and taking advantage of federal and state tax incentives, a self-installed solar system’s economic payback time is now shorter than ever before, typically within the 5-10 year range for most solar investments.

Once you know your system price, any financing costs, and the value of the electricity generated, it is possible to estimate an approximate payback time on your investment and know the ROI on buying your solar panels. With a more detailed model, it's possible to get an even more accurate number.

Jun 5th 2017This greatly depends on 3 main components.  
1.  Turnkey price of the system
2.  Grid Electricity costs per kWh
3.  Sunshine hours in the installation location

If you factor these 3 basic principals you can come up with a pretty straight forward ROI calculation.  If you add financing into the equation and other incentives from state and local governments then it can become more complex although not rocket science.  Typically Residential installations are about $1.50/Watt USD to $3.00/Watt USD.  In some locations of the globe ROI can be as low as 3 to 4 years.

Aug 3rd 2017Energy Performance Certificates
Energy Performance Certificates (EPCs) are needed whenever a property is:

built
sold
rented
You must order an EPC for potential buyers and tenants before you market your property to sell or rent.

In Scotland, you must display the EPC somewhere in the property, eg in the meter cupboard or next to the boiler.

An EPC contains:

information about a property’s energy use and typical energy costs
recommendations about how to reduce energy use and save money
An EPC gives a property an energy efficiency rating from A (most efficient) to G (least efficient) and is valid for 10 years.

Hi,can you help me please.I search for a franchisor of solar system.I leave in Tunisia and i want to become a prospective franchisee.I am waiting for your answer.
