The ideal angle varies by geographical location and season; thus, homeowners must assess their home’s position and surrounding obstructions to optimize performance. Planning for potential shading from trees or buildings is also a crucial aspect of system design. Ensuring that panels receive unobstructed sunlight can significantly enhance their productivity and, by extension, the overall effectiveness of the solar energy system.

5. CALCULATING REQUIRED WATTAGE

To determine the appropriate wattage for a residential solar system, an analysis of household energy consumption is necessary. Conducting a comprehensive energy audit helps in identifying usage patterns effectively. This audit will include evaluating the energy demands of different appliances and computing their cumulative energy usage.

Once monthly energy consumption is established, the total system wattage can be calculated by dividing the total monthly kWh by the average number of solar production hours. For example, if a household consumes 750 kWh monthly and enjoys an average of 5 peak sunlight hours daily, the calculation would resemble the following:
– Monthly energy requirement = 750 kWh
– Daily sun hours = 5 hours
– Daily energy required = 750 / 30 = 25 kWh
– Daily wattage needed = 25,000 / 5 = 5,000 watts

This output indicates that a solar panel system generating approximately 5,000 watts would be necessary to meet that household’s energy needs effectively.

6. COST FACTORS
