Telah dilakukan penelitian tentang pengaruh tutupan awan terhadap radiasi matahari di Kota Pontianak. Data yang digunakan adalah tutupan awan yang diperoleh dari satelite ECMWF (European Center for Medium-Range Weather Forecasts) dan radiasi matahari yang diperoleh dari satelite NOAA (National Oceanic and Atmospheric Administrasion"™s). Tujuan dari penelitian ini yaitu mengetahui pengaruh tutupan awan terhadap radiasi matahari dan mengetahui potensi energi matahari selama lima tahun (2012-2016). Penelitian ini menggunakan metode regresi linier sederhana yang menghasilkan nilai korelasi rata-rata bulanan sebesar -0,73 untuk tutupan awan rendah dan -0,22 untuk tutupan awan tinggi. Nilai korelasi -0,73 mempengaruhi radiasi matahari karena tutupan awan rendah lebih banyak memantulkan gelombang pendek dari matahari dan lebih banyak meneruskan gelombang panjang dari bumi, sedangkan nilai korelasi -0,22 sangat kecil mempengaruhi radiasi matahari karena tutupan awan tinggi lebih banyak meneruskan gelombang pendek dari matahari dan memantulkan gelombang panjang dari bumi. Dari penelitian ini diperoleh nilai rata-rata radiasi matahari bulanan di Kota Pontianak adalah sebesar 644,48 Watt/m2 sedangkan nilai rata-rata energi matahari bulanan sebesar 464,03 kWh/m2 per bulan.
