This work is part of the master in Energy system at Mälardalens University and was written during spring of 2018. The purpose of this degree project is to evaluate the needs when it comes to planning tools for Swedish installers of PV-system. The outcome from this survey will then be used to adapt an already existing planning tool to better fit the Swedish PV-market. The method used was first a survey trip to meet with 35 different installers to get their experience and thoughts about the Swedish PV-market, their planning process, and the planning tool QuickPlan.

The comments from the interviews were then used to adapt QuickPlan to the Swedish market. The features that were required to be fixed or updated in QuickPlan were updating the tax system, including another roof, calculating the payback period, calculating the saved CO2 emission for installing a PV-system, implementing heat pumps in the load profiles, implementing fuses and evaluating the radiation calculation within the tool. Those implementations were evaluated together with results describing what was affecting the suggested implementations.

It was also evaluated how this business model that includes the tool QuickPlan should be implemented to the Swedish PV-market or if it not ready for it yet. The results from the survey showed the importance of certain features in a planning tool for the Swedish installers. For the implementations, a solution was presented by comparing to others results. The conclusions show that the increased adaptation of the tool to the Swedish PV-market will make it more available for the installers and the business model was overall positive according to the interviewed persons.
