The first step in a renewable energy consultation for solar PV design is to assess the energy needs and goals of the client. This involves understanding their current energy consumption, desired level of energy independence, and any specific requirements they may have.

Once the energy needs are identified, the next step is to select the appropriate inverter for the solar PV system. The inverter is responsible for converting the direct current (DC) generated by the solar panels into alternating current (AC) that can be used to power electrical appliances. Factors such as efficiency, power output, and compatibility with the solar panels need to be considered during this selection process.

In addition to the inverter, battery storage is also an important consideration in renewable energy consultations. Batteries allow for the storage of excess energy generated by the solar PV system during the day, which can be used during periods of low sunlight or at night. The capacity and type of battery are determined based on the client's energy storage requirements and budget.

Another crucial aspect of the consultation is assessing the suitability of the client's roofing for solar PV installation. Factors such as orientation, shading, and structural integrity need to be evaluated to determine the optimal placement and configuration of the solar panels. This step ensures maximum energy generation and system efficiency.
