Octopus app does not calculate Go pricing when SolarPV enabled

[delboy711]

I have just started using the Octopus app and found the 'Import Go' costs are always £0.00.

I traced the problem to the function graph_load() the code block starting at line 816 tests for solarpv mode. If true it calculates costs for 'Agile' tariff, but not for 'Go' tariff. If solarpv mode is false it calculates for both tariffs.

This revised code block works for me.

            if (solarpv_mode) {
                // ----------------------------------------------------
                // Solar PV agile outgoing
                // ----------------------------------------------------
                // calculate half hour kwh
                let kwh_use = 0;
                let kwh_import = 0;
                let kwh_solar = 0;

                if (use_kwh[z]!=undefined && use_kwh[z-1]!=undefined) kwh_use = (use_kwh[z][1]-use_kwh[z-1][1]);
                if (import_kwh[z]!=undefined && import_kwh[z-1]!=undefined) kwh_import = (import_kwh[z][1]-import_kwh[z-1][1]);
                if (solar_kwh[z]!=undefined && solar_kwh[z-1]!=undefined) kwh_solar = (solar_kwh[z][1]-solar_kwh[z-1][1]);

                // limits
                if (kwh_use<0.0) kwh_use = 0.0;
                if (kwh_import<0.0) kwh_import = 0.0;
                if (kwh_solar<0.0) kwh_solar = 0.0;

                // calc export & self consumption
                let kwh_solar_used = kwh_use - kwh_import;
                let kwh_export = kwh_solar - kwh_solar_used;

                // half hourly datasets for graph
                data["use"].push([time,kwh_use]);
                data["import"].push([time,kwh_import]);
                data["export"].push([time,kwh_export*-1]);
                data["solar_used"].push([time,kwh_solar_used]);

                // energy totals
                total_kwh_import += kwh_import
                total_kwh_export += kwh_export
                total_kwh_solar_used += kwh_solar_used

                // costs

                let cost_import_go = data.go[2*(z-1)][1]*0.01;
                let cost_export = data.outgoing[2*(z-1)][1]*0.01*-1;

                if (show_carbonintensity) {
                    let co2intensity = data.carbonintensity[2*(z-1)][1];
                    let co2_hh = kwh_import * (co2intensity * 0.001)
