1)Price of installationUNITED KINGDOMIn United Kingdom, an average household usually needed 3kW or 4kW amount of solar system installed to produce enough electricity to cover their total energy usage. If the household is more than 3 people they should prepare more than euro 5,000 for the cost.Solar systems that is larger than 4kW are usually not recommended for residential properties because the need of roof space required to install them. 5kW+ solar systems are typically only installed on commercial buildings and cost upward of £8,000.The cost of solar panels has drop in recent years due to better technology and cheaper mass market production. Buying a solar panel now means you can save up to 70% on the cost of a solar panel purchased back in 2010. https://www.theecoexperts.co.uk/how-much-do-solar-panels-cost-ukMALAYSIA FiT encourages the adoption of renewable energy such as solar energy by households by enabling house owners to sell excess electricity generated from their homes to TNB (Tenaga Nasional Berhad), for example. For every 1 kWh, house owners could get between RM1.20 to 1.23. Moreover, homes with solar PV would obtain an additional 26 cents. Based on studies, a double storey house residential with 4kWp Solar Photovoltaic System(roof integrated) installed which cost up to RM50,000 in 2013, is expected to have 12.24% rate of ROI. It is possible for house owners to earn as much as RM700 per month if they could generate as much as 4kW peak of electricity from their houses.Although Malaysia is the world’s fourth largest photovoltaic modules producer, solar technology is not widely adopted here. One of reason is the cost of installing photovoltaic systems in Malaysia is expensive, even though the cost is falling at a rate of more than 10% per year. In 2005the cost of photovoltaic system per kW peak was RM31,410, falling to RM24,970 in 2007, and to RM20,439 in 2009. Today, the cost has reduced to about RM15,000 per kW peak –at a rate that still unaffordable to most Malaysians.   Weather                  Types of solar panelsTypes Of Solar PanelsEfficiency-RateAdvantagesDisadvantagesMonocrystalline ~20%Have the highest efficiency ratesThe most expensivePolycrystalline ~15%Process used to make polycrystalline silicon is simpler and cost lessSensitive to high temperatures and lower lifespan Thin-Film: Amorphous Silicon Solar Panels ~7-10% lower costs, easy to produce & flexibleshorter warranties & lifespanConcentrated PV Cell ~41%Very high performance & efficiency rateSolar tracker & cooling system needed (to reach high efficiency rate) https://www.greenmatch.co.uk/blog/2015/09/types-of-solar-panels Malaysia Solar Cell TypeAdvantagesDisadvantages monocrystallineProduce up to four times the amount of electricity as thin-film solar panelsThe entire circuit can break down if the solar panel is covered with shadepolycrytallineTend to have slightly lower heat tolerance than monocrystalline solar panelsNeed to cover a larger surface to outputThin-FilmEffective in hotter climateMay require more number of circuit combiners and fuses for DC writing         Climate http://www.ccsenet.org/journal/index.php/eer/article/viewFile/11739/11836In the UK there is an average at least 8 hours of sunlight a day. This increases to around 16 hours of light in the summer months. Solar panels are well suited to the British climate as it is temperate, meaning that there is very little extreme weather. If the temperature goes well above 30MH the solar panel could suffer,as the panels can overheat. Luckily we rarely see temperatures above 30MH, in the United Kingdom.                                                            The positive factor in the efficiency of solar panels can also caused by the frequent rainfall in the UK. Rain does not limit the output of solar panels and it can actually make them more efficient by keeping them clean of dust and debris. The only weather condition fairly frequent in the UK which could negatively affect solar panel output is overcast and cloudy. When there are a lot of clouds in the sky it is harder for the sunlight to reach the surface of your solar panels. However, even on overcast days, solar panels can still produce around a third of their usual output using the daylight that does reach them.

CLIMATEMalaysia lies in the tropical region between 1o N and 7o N, and 100o E and 119o. Malaysia’s weather condition in  is very suitable for photovoltaic implementation, this is because the weather condition is almost predictable and the sunlight is available for more than ten hours daily with almost six hours of direct sunlight.Commonly in Malaysia, photovoltaic panels were installed fix to the building either on the roof this installation considered as static system. These static systems only maximize sun availability at certain time during daytime. In the UK there is an average at least 8 hours of sunlight a day. This increases to around 16 hours of light in the summer months. Solar panels are well suited to the British climate as it is temperate, meaning that there is very little extreme weather.
