KEY POINTS: Is the owner of the roof the owner of the solar PV system? Have you assessed the revenue streams or avoided costs of the project? Have you assessed system configuration options for a specific project? Are you aware of the costs of the different system configurations? Do you Read more
The formula for calculating the electricity demand in kWh is: Demand = power consumption per hour x operating hours per day Equipment Power consumption Assumed operating hours per day No. of equipment Power consumption per day Lighting 25 W 3 h 5 375 Wh Lighting (LED) 6 W per Read more
Site-specific criteria and trade-offsThe site-specific criteria are similar to the criteria covered in the privious blog roof requirement for a Solar system. At this stage, a key question might be how to mount the solar PV system on the roof and if a system should perhaps be elevated.Depending on the Read more
The various types of commercially available solar PV modules, including their appearance, maximum efficiencies, manufacturers and possible module designs Module technology Maximum efficiency (manufacturer) Appearance Remarks mono-Si 21.5% (SunPower) homogeneous dark blue framed glass-foil and frameless glass-glass or foil- foil laminates Read more
A residential solar PV installation (SHS/PPS) typically consists of the following main components: Solar PV modulesSolar cells use sunlight to produce electricity. Solar PV modules consist of several solar cells, which can be connected in series and in parallel to achieve the desired module output power. Solar PV modules work Read more
Successful Solar house system implementation requires collaboration among various parties. Profit, quality of life and social benefit are the driving forces for stakeholders. Key stakeholders in worldwide residential PV expansion are described in the following.

Various business models exist, mainly for grid-connected residential PV installations. A short overview is given below: Business model Description Self-consumption Residential owners produce electricity from solar PV and decrease their electricity costs; they become less reliant on utilities and can sell the excess electricity. Feed-in based System Read more
Permitting and licensing requirements determine the eligibility of components and have to be considered for the technology assessment and system configuration. Typical requirements of regulatory frameworks are described in this section. Applicable norms and standardsSolar PV systems are electrical generators. For this reason, special attention has to be paid to Read more
In general, the application of solar PV systems is considered to be positive, as it is a sustainable technology. Converting solar irradiation into electricity using solar PV technology does not result in air, water or ground pollution and does not endanger animal or human health.The environmental impacts are associated more Read more
