automated camera for daily photos of construction site

Hello everyone, looks like we will start on building our dream home this year. I do want to set up a raspberry for automated photo shooting from the construction site. One picture per day is enough, I do want to create a timelapse video afterwards. The new neighbour is a friend, he allowed me to set up the camera in his house facing the construction site. Only problem he does not have a power supply at his window...

Anyone having experience with a solar module and a battery to power the raspi? Feel free to share your jdeas!
