  1. Hi Oliver, you can record screens with Powerpoint, otherwise I use FlashBack screen recorder.
  2. Hi 👍 I'm trying to figure out how; in the cashflow table, the Feed-in / Export Tariff value & Electricity Savings values are calculated please? I checked the help site but I don't think the page covers this; https://help.valentin-software.com/pvsol/calculation/financial-analysis/ As a back-story; I'm trying to replicate the PV Sol values just out of interest and because we hand this information to customers so best to understand it completely, although I'm not the best at maths. I'm about £1.00-£15.00 out on the first year. I've attached a link to the file I'm using to try and replicate the PV Sol values below. I've highlighted the cells I want to match in Purple, they are in the 'Year' tab and 'PV Cashflow data' tab. It's possible my formulas are using the wrong data column in the .csv file - there are so many similar columns. Or there is something else I don't exactly know, but there is only so much digging before I ask for advice. Thank you! https://cornwallsuperhomes-my.sharepoint.com/:x:/g/personal/jordan_nakedsolar_co_uk/EVT48ZF4P_xHskgosU4KJIgBBAtYPF7JbLUJYEbeuRZpeA?e=exQ7aI

    PV*SOL Wishlist

    Hello there This is just something we notice everytime we export the PV Sol presentation. It's a nice to have however not necessary. We issue the PV Sol report to all our customers and there are a few items that don't need on the report. For example; we like the Project Overview, yet we don't need the schematic diagram. We like the financial analysis, yet don't need the Electricity Cost Trend diagram. Neither the Schematic diagram or the Electricity Cost Trend figure are items that can be unticked in the Presentation Options. It would be nice to opt out of these diagrams please. Also another one please, the PV Sol report can allready explain relationships of self-consumption, import and export. However I think there is a missing nice illustration to tell the story in a more digestible way. For example, I like the way the SolarEdge monitoring portal illustrates annual values in this way. It would be great to provide customers an illustration of annual values in the same way as shown below, in a PV Sol report.

    Is it possible to change the blue sky texture to a different texture? The existing texture is great, yet just for visual reasons, might be nice to set a sunset/sunrise/cloudy/other skyboxes textures. Thanks, Jordan

    Sun Position graphs

    Hello, just putting this question out there; how are Sun position graphs made, and can they be made from PV Sol? Is there a way of illustrating the sun path in PV Sol? The graph below is copied from the PV Sol software help page; https://help.valentin-software.com/pvsol/calculation/irradiation/sun-position/ *and this one is from https://thumbs.dreamstime.com/b/sun-path-illustration-18273849.jpg

    PV Sol best images

    Hello everyone, please share your best image/design created with PV Sol. Why? - To show and explain the best ways to create visually attractive solar systems. This is mine created with amazing PV Sol; A new-build housing development in the UK - instead of roofing with attractive expensive Cornish slate, the contractor wants to reduce their material costs by installing in-roof panels and experiment with how 'green' they could get. We were able show the contractor thier project in PV Sol by;Importing the site plan, altering the orientation and referencing elevation plans to recreate the neibourhood. Orange buildings highlight PV systems within public view, lighter buildings highlight PV systems with limited public view, grey buildings highlight properties outside consideration. The image went down so well it was reported the contractor specially printed this at poster size to show and tell to Prince Charles of Wales.

(Unlike my inception of that chart ahha). Quick question if anyone is up for it please; speaking to my colleagues we suggest Eastern orientations should generate more kWh than West generation because the panels experience less heat losses as they're cooler in the morning. What else would suggest a difference in generation between the East and West orientations? I'm guessing this is a solar designer elementary question. Thank you!

    Pitch and orientation

    Hi Martin, Thank you for your response!! Aye I've attached the file I've been using. Using version 2020.5.130. I'll take a look at the Severn England climate data. Thanks again! Yours, Jordan PV Sol Orientation and Pitch.pvprj
  14. Hi everyone & Valentin, we're creating an orientation and pitch chart to show others clearly the kind of performances to expect. Like a compass - difference in Orientation axis follows around the chart, and difference in pitch runs from the centre to the circumference in smaller to larger circles (0 degrees to 80 degrees pitch). So the first circle from the centre represents 10 degrees pitch, the second circle from the centre represents 20 degrees pitch and so on. It's quite smart and will hopefully give clarity to others than Northern facing systems still produce an acceptable level of generation. This is what we've made so far as an example; ...All we've done above is estimated what we think the chart would look like. We'd like to make a PV Sol experiment on what the chart would actually look like. So to do this I'm noting down the PV Sol PV Generator Energy (AC Grid) value for every different combination of orientation and pitch. I've made one for Newquay UK using 14 SunPower Maxeon2 350 panels and a solis 3.68kw inverter (no shading). Just as an illustration; Just using my simple head I would have initially thought East and West orientations would mirror eachother down the South line, as in East and West would give equal or similar energy - lets say 20° due West would provide the same amount of energy as 20° due East. But then this is Newquay, there's the ocean to the West which would skew the results to favour the West though a big water body Albedo. So then I tried other locations; Baldhu UK, Norfolk UK, Riyadh SA and PV Sol shows West orientations generate more PV Generator Energy (AC Grid) than East orientations. Couple of questions please; is there a location in the world where East and West orientations match PV Generator Energy (AC Grid)? am I missing something here... generally speaking is it normal for West orientations to generate more than East? Thank you everyone!! Yours, Jordan
